Question

jayesh is as much younger to anil as he is older to prashant.if the sum of ages of anil and prashant is 48 years then what is the age of jayesh?

Answer 1

let the age of  jayesh be x.
and the difference between the age of anil and jayesh be y years 

Now the age of anil is   x+y
and the age of prashant is x-y    [since jayesh is as younger to anil as he is older to prashant]

now [age of prashant] +[age of anil] = 48
      x+y + x-y = 48
      2x = 48
        x= 24
 age of  jayesh is 24.

Answer 2

let jayesh be x yrs older than anil 
so given difference between ages of prashant and anil = 2x
so given 2x = 48
x = 24 so age of jayesh is 24 yrs
