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

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.
