Question

father present age is 4 times sohana's age, after 5 years father's age will be 3 times soham's age. Find their present age.

Answer 1

father age=x
sohana age=y
x=4y
x+5=3(y+5)
x+5=3y+15
x-3y=10
4y-3y=10
y=10
sohana age is 10 years
father age is 40 yrs

Answer 2

Let the soham's age be 'x'
Then the father's age will be '4x'
After 5 yrs their age will become 'x+5','4x+5' respectively

A.T.Q, 3(x+5) = 4x+5
3x+15 = 4x+5
4x-3x = 15-5
x=10
Therefore, Soham's age is 10 & Father's age will be 10*4=40
