Answer: Option A. -> subtracting
:

Answer: Option C. -> i and iii only
:
C
i)0 + 2 = 2 which is a whole number. Also, whole numbers are closed under addition.
ii)0 ÷ 49843 = 0 which is a whole number.
iii)98645 × 5678 = 5678 × 98645
This represents commutative property of multiplication.

Answer: Option A. -> True
:
A
If you divide something by 2 you divide that thing into 2 parts. If you divide something by 4 you divide that thing into 4 parts. Now if you divide something by 0, you cannot divide that thing into 0 parts. So a division by 0 is undefined and Rahulis correct.

Answer: Option A. -> True
:
A
Yes it is correct.
9 can be written as 10 - 1
So 117 + 9 = 117 + 10 - 1
Again (117+ 10) = 127, so (117+ 10) - 1= 127 - 1

Answer: Option C. -> 23
:
C
The number of whole numbers between any two numbers
= (thedifference between the numbers) -1.
The difference between 9900 - 9876 is 24 and 24 -1 = 23.
So, there are 23 whole numbers are there between 9876 and 9900.

Answer: Option D. -> 7
:
D
The difference between two consecutive numbers is 1 and let's consider this difference to be a one step.
The catis at number 3 and the ratis at number 10. Thedifference between 10 and 3 is 7, therefore the rat is 7 steps away from the cat.
