#### Question No 2

In the division calculation 952 473 Ã· 18, which two adjacent digits should be swapped in order to increase the result by 100?

Solution!
If after division by 18 the number has to be increased by 100, then before the division it needs to be increased by 18 Ã— 100 = 1800. So we need to find two adjacent digits in the number 952 473 which when swapped increase it by 1800. If 952 473 is increased by 1800 it becomes 952 473 + 1 800 = 954 273. We obtain 954 273 from 952 473 by swapping the adjacent digits 2 and 4.

#### Question No 3

The sum of age 5 children born at the interval of 2 year each is 40 year. Find out the age of eldest child?

Solution!
let's age of youngest child = x
Then the age of 5 children can be written as x,( x + 2) ,(X + 4 ),(x + 6) and( X + 8).
Age of elders child = X + 8
Then ,
X + (X + 2 )+ (X+ 4) +( X + 6) + (X + 8) = 40
5 X + 20 = 40
5 X = 40 - 20
X = 20 / 5
X = 4
Age of elders child = X + 8
4 + 8 = 12.
