Question

The sum of neelu and sheelu present age is 23 years. If neelu is older than sheelu by 5 years. Find the present age.

Answer 1

Given: Sum of present ages of Neelu and Sheelu = 23 years

           Neelu is older that Sheelu by 5 years

Let: Present age of Neelu = x years

      Present age of Sheelu = y years

Solution: According to the question,

        x + y = 23 or x = 23 - y     ...(1)

also, x = y + 5                            ...(2)

Adding equation (1) and (2)

x + x = 23 - y + y + 5

2x = 23 + 5

2x = 28

x = 14

Hence, present age of Neelu = 14 years

putting value of x in equation (1)

14 = y + 5

y = 14 - 5

  = 9

Hence, present age of Sheelu = 9 years
