Total Distance travelled by the student from school to home and from home to school is = 2 x 1875 = 3750 m

Distance travelled by the student in six days is = 3750 m x 6 – 22500 m = 22 km 500 m.

Therefore, the total distance covered in 6 days = 22 km 500 m.

Question 36.

A merchant had ₹78,592 with her. She placed an order to purchase 40 radio sets at ₹1200 each. How much total money will remain with her after the purchase?

Amount of money present with the merchant = ₹78,592

Total Number of the radio sets = 40

Price of one of the radio set = ₹1200

Therefore, the cost of 40 radio sets = ₹1200 x 40 = ₹48,000

Remaining money left with the merchant = ₹78,592 – ₹48000 = ₹30,592

Hence, the amount of ₹30,592 will remain with her after purchasing the following radio sets.

Question 37.

A vessel has four litres and 500 ml of curd. How many total glasses, each of 25 mL capacity, can be filled?

(ii) 796 – 314

(iii) 12,904 + 2,888

(iv) 28,292 – 21,496

Rounding off 730 nearest to hundreds = 700

Rounding off 998 nearest to hundreds = 1,000

∴ 730 + 998 = 700 + 1000 = 1700

Rounding off 796 nearest to hundreds = 800

Rounding off 314 nearest to hundreds = 300

∴ 796 – 314 = 800 – 300 = 500

Rounding off 12,904 nearest to thousands = 13000

Rounding off 2888 nearest to thousands = 3000

∴ 12,904 + 2,888 = 13000 + 3000 = 16000

Rounding off 28,292 nearest to thousands = 28,000

Rounding off 21,496 nearest to thousands = 21,000

∴ 28,292 – 21,496 = 28,000 – 21,000 = 7,000

The total amount a person had was = ₹ 1000000

The total amount he spent on a colour T.V. was = ₹ 16580

The amount he spent on a motorcycle was = ₹ 45890

The amount he spent on a flat was = ₹ 870000

∴ Total amount he spent is = ₹ (16580 + 45890 + 870000) = ₹ 932470

Thus, the total amount left with him = ₹ 1000000 – ₹ 932470 = ₹ 67530

Question 60.

Out of 180000 tablets of Vitamin A, a total of 18734 are distributed among the students in the district. Find the total number of remaining vitamin tablets.

Thus, you can trust our solved answer Pdfs without any worries.

Class 6 Maths Chapter 1 Extra Questions Concepts 

Before we proceed to tell our students about the crucial questions, we would like to give them a little bit of description about the topics they will cover in this chapter. Given below are the main topics which students will be learning as they go through this chapter.

There are many definitions that one can look for if they ask someone what the meaning of numbers is. Well, for starters numbers are the things which are used by humans to count. For example, if you see a single butterfly so if you count in terms of number, it is 1. 

Also, the number system starts from 1, and it goes to infinity there is no end to the numbers. One can go as far as they wanted. With numbers, you can count things, add different products and much more. In terms of mathematics, numbers are the building blocks of real mathematics that we study and learn today.

Ascending Order 

This is one of the new topics and mathematical functions that students get to use to find out the answer. In ascending order, one has to arrange different numbers one after the other depending on their power, which means there are 5 different numbers such as 5, 22, 48, 99, and 27. Then you put these numbers in ascending order by seeing which number is the smallest from the given number and putting it in the first place. 

Here in the given example 5 is the smallest number from all the other numbers. On the other hand, 99 is the most significant number, but it’s in the fourth position, so we put it last. Now we have 22, 48 and 27. We now arrange them by choosing the smallest and the biggest, and that’s how you write the ascending order for the given numbers. The final number line will be 5,22,27,48, and 99.

Descending Order 

The descending order is the total opposite of the ascending order. In this, you need to put the highest number in the first place and the smallest number at the end. The descending order means first comes the biggest, and from there, the numbers will only become small, and the last digit will be the smallest from the whole set of numbers.  

For example, there are 5 numbers present in the box which are 22, 48, 99, 5 and 27. So if a student needs to arrange them, he needs to put the highest number in front and the smallest number at the back or end. So now the number line will look like this. 99, 22, 48, 27 and 5. Just like that, we use the descending order again, and this time we get 99, 48, 27, 22 and 5. This is the descending order of the example.  

Place Value 

A place value defines the positional notation of a digit’s position. This might sound complicated, but it’s nothing to be worried about. Let's clear it by taking an example. Take a big number like 53210. Here let’s try to find out the place value for each single number present.

0 = zero place

1 = one’s place

2 = two’s place

3 = hundered’s place.

4 = thousand’s place

5 = ten thousand’s place. 

The place value is one of the most important concepts as it introduces you to the currency system, and there are two different place values, but in this chapter, we are only discussing Indian place value system.

1. A book exhibition was held for four days in a school. The number of tickets sold at the counter on the first, second, third and final day was respectively 1094, 1812, 2050 and 2751. Find the total number of tickets sold on all four days.

Number of tickets sold on 1st day = 1094

Number of tickets sold on 2nd day = 1812

Number of tickets sold on 3rd day = 2050

Number of tickets sold on 4th day = 2751

Hence, the total number of tickets sold on all four days = 1094 + 1812 + 2050 + 2751 = 7707 tickets

2. Shekhar is a famous cricket player. He has so far scored 6980 runs in test matches. He wishes to complete 10,000 runs. How many more runs does he need?

Shekhar scored = 6980 runs

He wants to complete = 10000 runs

Runs needed to score more = 10000 – 6980 = 3020

Hence, he needs 3020 more runs to score

3. In an election, the successful candidate registered 5,77,500 votes, and his nearest rival secured 3,48,700 votes. By what margin did the successful candidate win the election?

No. of votes secured by the successful candidate = 577500

No. of votes secured by his rival = 348700

Margin by which he won the election = 577500 – 348700 = 228800 votes

∴ The successful candidate won the election by 228800 votes

4. Kirti bookstore sold books worth Rs 2,85,891 in the first week of June and books worth Rs 4,00,768 in the second week of the month. How much was the sale for the two weeks together? In which week was the sale greater and by how much?

Price of books sold in the first week of June = Rs 285891

Price of books sold in the second week of June = Rs 400768

No. of books sold in both weeks together = Rs 285891 + Rs 400768 = Rs 686659

The sale of books is the highest in the second week.

Difference in the sale in both weeks = Rs 400768 – Rs 285891 = Rs 114877

∴ Sale in the second week was greater by Rs 114877 than in the first week.

5. Find the difference between the greatest and the least 5-digit number that can be written using the digits 6, 2, 7, 4, and 3 each only once.

Digits given are 6, 2, 7, 4, 3

Greatest 5-digit number = 76432

Least 5-digit number = 23467

Difference between the two numbers = 76432 – 23467 = 52965

∴ The difference between the two numbers is 52965.

6. A machine, on average, manufactures 2,825 screws a day. How many screws did it produce in the month of January 2006?

Number of screws manufactured in a day = 2825

Since January month has 31 days,

The number of screws manufactured in January = 31 × 2825 = 87575

Hence, the machine produced 87575 screws in the month of January 2006.

7. A merchant had Rs 78,592 with her. She placed an order for purchasing 40 radio sets at Rs 1200 each. How much money will remain with her after the purchase?

Total money the merchant had = Rs 78592

The number of radio sets she placed an order for purchasing = 40 radio sets

Cost of each radio set = Rs 1200

So, cost of 40 radio sets = Rs 1200 × 40 = Rs 48000

Money left with the merchant = Rs 78592 – Rs 48000 = Rs 30592

Hence, money left with the merchant after purchasing radio sets is Rs 30592.

8. A student multiplied 7236 by 65 instead of multiplying by 56. By how much was his answer greater than the correct answer?

Difference between 65 and 56, i.e. (65 – 56) = 9

The difference between the correct and incorrect answer = 7236 × 9 = 65124

Hence, by 65124, the answer was greater than the correct answer.

9. To stitch a shirt, 2 m 15 cm cloth is needed. Out of 40 m cloth, how many shirts can be stitched and how much cloth will remain?

The total length of the cloth = 40 m

= 40 × 100 cm = 4000 cm

Cloth required to stitch one shirt = 2 m 15 cm

= 2 × 100 + 15 cm = 215 cm

Number of shirts that can be stitched out of 4000 cm = 4000/215 = 18 shirts

Hence, 18 shirts can be stitched out of 40 m, and 1 m 30 cm of cloth is left.

10. Medicine is packed in boxes, each weighing 4 kg 500g. How many such boxes can be loaded in a van which cannot carry beyond 800 kg?

Weight of one box = 4 kg 500 g = 4 × 1000 + 500

Maximum weight carried by the van = 800 kg = 800 × 1000

Hence, the number of boxes that can be loaded in the van = 800000/4500 = 177 boxes

11. The distance between the school and a student’s house is 1 km 875 m. Every day, she walks both ways. Find the total distance covered by her in six days.

Distance covered between the school and her house = 1 km 875 m = 1000 + 875 = 1875 m

Since the student walks both ways,

The distance travelled by the student in one day = 2 × 1875 = 3750 m

Distance travelled by the student in 6 days = 3750 m × 6 = 22500 m = 22 km 500 m

∴ The total distance covered by the student in six days is 22 km and 500 m.

12. A vessel has 4 litres and 500 ml of curd. In how many glasses, each of 25 ml capacity, can it be filled?

Quantity of curd in the vessel = 4 l 500 ml = 4 × 1000 + 500 = 4500 ml

Capacity of 1 glass = 25 ml

∴ Number of glasses that can be filled with curd = 4500 / 25 = 180 glasses

Hence, 180 glasses can be filled with curd.

Exercise 1.3 Page NO: 23

1. Estimate each of the following using the general rule:

(a) 730 + 998 (b) 796 – 314 (c) 12904 + 2888 (d) 28292 – 21496

Make ten more such examples of addition, subtraction and estimation of their outcome.

(a) 730 + 998

Round off to hundreds

730 rounds off to 700

998 rounds off to 1000

Hence, 730 + 998 = 700 + 1000 = 1700

(b) 796 – 314

796 rounds off to 800

314 rounds off to 300

Hence, 796 – 314 = 800 – 300 = 500

(c) 12904 + 2888

Round off to thousands

12904 rounds off to 13000

2888 rounds off to 3000

Hence, 12904 + 2888 = 13000 + 3000 = 16000

(d) 28292 – 21496

28292 round off to 28000

21496 round off to 21000

Hence, 28292 – 21496 = 28000 – 21000 = 7000

Ten more such examples are

(i) 330 + 280 = 300 + 300 = 600

(ii) 3937 + 5990 = 4000 + 6000 = 10000

(iii) 6392 – 3772 = 6000 – 4000 = 2000

(iv) 5440 – 2972 = 5000 – 3000 = 2000

(v) 2175 + 1206 = 2000 + 1000 = 3000

(vi) 1110 – 1292 = 1000 – 1000 = 0

(vii) 910 + 575 = 900 + 600 = 1500

(viii) 6400 – 4900 = 6000 – 5000 = 1000

(ix) 3731 + 1300 = 4000 + 1000 = 5000

(x) 6485 – 4319 = 6000 – 4000 = 2000

2. Give a rough estimate (by rounding off to the nearest hundreds) and also a closer estimate (by rounding off to the nearest tens):

(a) 439 + 334 + 4317 (b) 108734 – 47599 (c) 8325 – 491 (d) 489348 – 48365

Make four more such examples.

(a) 439 + 334 + 4317

Rounding off to the nearest hundreds

439 + 334 + 4317 = 400 + 300 + 4300

Rounding off to the nearest tens

439 + 334 + 4317 = 440 + 330 + 4320

(b) 108734 – 47599

108734 – 47599 = 108700 – 47600

108734 – 47599 = 108730 – 47600

(c) 8325 – 491

8325 – 491 = 8300 – 500

8325 – 491 = 8330 – 490

(d) 489348 – 48365

489348 – 48365 = 489300 – 48400

489348 – 48365 = 489350 – 48370

Four more examples are as follows:

(i) 4853 + 662

4853 + 662 = 4800 + 700

4853 + 662 = 4850 + 660

(ii) 775 – 390

775 – 390 = 800 – 400

775 – 390 = 780 – 400

(iii) 6375 – 2875

6375 – 2875 = 6400 – 2900

6375 – 2875 = 6380 – 2880

(iv) 8246 – 6312

8246 – 6312 = 8200 – 6300

8246 – 6312 = 8240 – 6310

3. Estimate the following products using the general rule:

(a) 578 × 161

(b) 5281 × 3491

(c) 1291 × 592

(d) 9250 × 29

Rounding off by general rule

578 and 161 rounded off to 600 and 200, respectively

____________

_____________

5281 and 3491 rounded off to 5000 and 3500, respectively

1291 and 592 rounded off to 1300 and 600, respectively

______________

9250 and 29 rounded off to 9000 and 30, respectively

A book exhibition was held for four days in a school. The number of tickets sold at the counter on the first, second, third, and final day was respectively 1094, 1812, 2050, and 2751. Find the total number of tickets sold on all the four days.

Tickets sold on 1 st day = 1094

Tickets sold on 2 nd day = 1812

Tickets sold on 3 rd day = 2050

Tickets sold on 4 th day = 2751

Total tickets sold = 1094 + 1812 + 2050 + 2751

∴ Total tickets sold = 7,707

Shekhar is a famous cricket player. He has so far scored 6980 runs in test matches. He wishes to complete 10, 000 runs. How many more runs does he need?

Runs scored so far = 6980

Runs Shekhar wants to score = 10,000

More runs required = 10,000 − 6980

∴ Shekhar requires 3,020 more runs.

NCERT Solution for Class 6 math - Knowing Our Numbers 16 , Question 2

In an election, the successful candidate registered 5, 77, 500 votes and his nearest rival secured 3, 48, 700 votes. By what margin did the successful candidate win the election?

Votes secured by successful candidate = 5,77,500

Votes secured by rival = 3,48,700

Margin = 5,77,500 − 3,48,700

∴ Margin = 2,28,800

Kirti bookstore sold books worth Rs 2,85,891 in the first week of June and books worth Rs 4,00,768 in the second week of the month. How much was the sale for the two weeks together? In which week was the sale greater and by how much?

Value of Books sold in 1 st week = Rs 2,85,891

Value of books sold in 2 nd week = Rs 4,00,768

Total sale = Sale in 1 st week + Sale in 2 nd week

= 2,85,891 + 4,00,768

The sale for the two weeks together was 6,86,659.

Since 4,00,768 > 2,85,891, sale in 2 nd week was greater than 1 st week.

∴ The sale in 2 nd week was larger than the sale in 1 st week by Rs 1,14,877.

Question 5:.

Find the difference between the greatest and the least number that can be written using the digits 6, 2, 7, 4, 3 each only once.

Greatest number = 76432

Smallest number = 23467

Difference = 76432 − 23467

Therefore, the difference between the greatest and the least number that can be written using the digits 6, 2, 7, 4, 3 each only once is 52,965.

Question 6:

A machine, on an average, manufactures 2,825 screws a day. How many screws did it produce in the month of January 2006?

Screws produced in one day = 2,825

Days in January = 31

Screws produced in 31 days = 2825 × 31

Therefore, screws produced during Jan, 06 = 87,575

Question 7:

A merchant had Rs 78,592 with her. She placed an order for purchasing 40 radio sets at Rs 1200 each. How much money will remain with her after the purchase?

Cost of one radio set = Rs 1200

Cost of 40 radio sets = 1200 × 40 = Rs 48000

Money with Merchant = Rs 78,592

Money spent = Rs 48,000

Money left = 78592 − 48000

Therefore, Rs 30,592 will remain with her after the purchase.

Question 8:

A student multiplied 7236 by 65 instead of multiplying by 56. By how much was his answer greater than the correct answer? (Hint: Do you need to do both the multiplications?)

Difference between 65 and 56 = 9

Difference in the answer = 7236 × 9

Therefore, his answer was greater than the correct answer by 65,124.

Question 9:

To stitch a shirt, 2m 15 cm cloth is needed. Out of 40 m cloth, how many shirts can be stitched and how much cloth will remain? (Hint: convert data in cm.)

2 m 15 cm = 215 cm (1 m = 100 cm)

40 m = 40 × 100

Cloth required for one shirt = 215 cm

Number of shirts that can be stitched out of 4000 cm = 4000 ÷ 215

Therefore, 18 shirts can be made. 130 cm, i.e. 1 m 30 cm, cloth will remain.

Question 10:

Medicine is packed in boxes, each weighing 4 kg 500 g. How many such boxes can be loaded in a van which cannot carry beyond 800 kg?

1 kg = 1000 g

4 kg 500 g = 4500 g

800 kg = 800 × 1000 = 800000 g

Number of boxes that can be loaded in the van = 800000 ÷ 4500

Hence, 177 boxes at maximum can be loaded in the van.

NCERT Solution for Class 6 math - Knowing Our Numbers 17 , Question 10

Question 11:

The distance between the school and the house of a student’s house is 1 km 875 m. Everyday she walks both ways. Find the total distance covered by her in six days.

Distance between school and house = 1 km 875 m

Now, 1 km = 1000 m

1 km 875 m = 1875 m

Distance covered each day = 1875 × 2 = 3750 m

Distance covered in 6 days = 3750 × 6

Therefore, distance covered in 6 days = 22,500 m

= 22.5 km or 22 km 500 m

Question 12:

A vessel has 4 litres and 500 ml of curd. In how many glasses, each of 25 ml capacity, can it be filled?

Capacity of vessel = 4 l 500 ml

= 4500 ml (1 l = 1000 ml)

Capacity of a glass = 25 ml

Number of glasses that can be filled = 4500 ÷ 25

∴ 180 glasses can be filled.
