The age of a Mohan is three times the sum of the ages of his two sons. Five years hence, his age will be double of the sum of the ages of his sons. The father's present age is?
Let the sum of ages of two sons be x years
Age of man = 3xyears
After 5 years age of the man =(3x+5) years
Sum of ages of two sons =(x+10) years
Given, (3x+5) =2(x+10)
⇒ (3x+5) =2x+20
⇒ x=15
Hence 3x=3(15) = 45
∴ Present age of father is 45years.
