John's present age is one fourth of his father's age two years ago. John’s father’s age will be twice Raman's age after 10 years. If Raman's 12th birthday was celebrated 2 years ago, then what is John's present age?

Let, John's present age be "x" years.

So, age of father two years ago = 4x

So, current age of father = (4x+2) years

It is given, Raman's 12th birthday was celebrated 2 years ago, so Raman's current age = 12+2 = 14 years

So, Raman's age after 10 years = 14+10 = 24 years

So, John's father's age after 10 years = 2*24 = 48 years

So, present age of John's father = (48-10) years = 38 years

So, 4x+2=38

or, 4x=36

or, x=9

So, John's present age is 9 years.
