Rs Aggarwal Class 6 Math Solution Chapter 3 Whole Number, Test Paper
Test Paper
1. How many whole numbers are there between 1064 and 1201?
Solution:
Number of whole numbers between 1201 and 1064 = ( 1201 − 1064 ) − 1
= 137 − 1
= 136
2. Fill in the blanks.
1 0 0 0 0 0 0 - * * * * 1 * 7 2 4 2 *
Solution:
1 0 0 0 0 0 0 - 2 9 5 7 1 9 7 2 4 2 9
3. Use distributive law to find the value of 1063 × 128 − 1063 × 28.
Solution:
Using distributive law, we have:
1063 × 128 − 1063 × 28
= 1063 × (128 − 28)
= 1063 × 100
= 106300
4. Find the product of largest 5 -digit number and the largest 3 -digit number using distributive law.
Solution:
Largest 5-digit number = 99999
Largest 3-digit number = 999
By using distributive law, we have:
Product = 99999 × 999
= 99999 × (1000 − 1) [By using distributive law]
= 99999 × 1000 − 99999 × 1
= 99999000 − 99999
= 99899001
5. Divide 53968 by 267and check the result by the division algorithm.
Solution:
6. Find the largest 6-digit number divisible by 16.
Solution:
Largest 6-digit number = 999999
Now, we divide 999999 by 16
Remainder = 15
Required Largest six-digit number = 999999 − 15 = 999984.
7. The cost price of 23 TV sets is Rs. 570055. Find the cost of each such set.
Solution:
Cost price of 23 TV sets = Rs 5,70,055
Cost price of 1 TV set = 570055 ÷ 23
∴ Cost of one TV set = Rs. 24785.
8. What least number must be subtracted from 13801 to get a number exactly divisible by 87?
Solution:
First we will divide 13801 by 87
Remainder = 55
Required number is 55, that should be subtracted from 13801 to get a number divisible by 87.
9. The value of (89 × 76 + 89 × 24) is
(a) 890
(b) 8900
(c) 89000
(d) 10420
Solution: Correct option is (b) 8900
(89 × 76 + 89 × 24)
= 89 × (76 + 24)
= 89 × 100
= 8900
10. On dividing a number by 53 we get 8 as quotient and 5 as remainder. The number is
(a) 419
(b) 423
(c) 429
(d) none of these
Solution: Correct option is (c) 429
Divisor = 53, Quotient = 8, Remainder = 5 and Dividend = ?
Now, Dividend = Quotient × Divisor + Remainder
= 8 × 53 + 5
= 429
11. The whole number which has no predecessor is
(a) 1
(b) 0
(c) 2
(d) none of these
Solution: Correct option is (b) 0.
The whole number which has no predecessor is 0.
i.e., 0 − 1 = −1, which is not a whole number.
12. 67 + 33 = 33 + 67 is an example of
(a) closure property
(b) associative property
(c) commutative property
(d) distributive property
Solution: Correct option is (c)
67 + 33 = 33 + 67 is an example of commutative property of addition.
13. Additive inverse of 36 is
(a) `frac\{1}{ 36}`
(b) 0
(c) -36
(d) none of these
Solution: Correct option is (c) -36
The additive inverse of 36 is −36.
i.e., 36 + (−36) = 0
14. Which of the following is not zero?
(a) 0 × 0
(b) `frac\{0}{2}`
(c) `frac\{8 - 8}{2}`
(d) 2 + 0
Solution: Correct option is (d) 2 + 0
15. The predecessor of the smallest 3-digit number is
(a) 999
(b) 100
(c) 101
(d) 99
Solution: Correct option is (d) 99
Smallest three-digit number = 100
∴ Predecessor of 100 = 100 − 1 = 99
16. The number of whole number between the smallest whole number and the greatest 2-digit number is
(a) 88
(b) 98
(c) 99
(d) 101
Solution: Correct option is (b) 98.
Smallest whole number = 0
Greatest two-digit number = 99
Number of whole numbers between 0 and 99 = (99 − 0 ) − 1 = 98
17. Fill in the blanks.
(i) The smallest natural number is .
(ii) The smallest whole number is .
(iii) Division by is not defined.
(iv) is a whole number which is not a natural number.
(v) is a whole number which is not a natural number.
Solution:
(i) The smallest natural number is 1.
(ii) The smallest whole number is 0.
(iii) Division by 0 is not defined.
(iv) 0 is a whole number which is not a natural number.
(v) 1 is the multiplicative identity for whole numbers.
18. Write ' T ' For true and 'F' for false in each of the following:
(i) 0 is the smallest natural number.
(ii) Every natural number is a whole number.
(iii) Every whole number is a natural number.
(iv) 1 has no predecessor in whole numbers.
Solution:
(i) F (false). 0 is not a natural number.
(ii) T (true).
(iii) F (false). 0 is a whole number but not a natural number.
(iv) F (false). 1 − 1 = 0 is a predecessor of 1, which is a whole number.
