Answer 1

Answer:

let the age of elder son be X.

age of father be 2 X .

age of younger son be X-15.

ATQ

after ten years father will be three times his younger son.

so, after ten years father age will be 2X+10 year and younger son age would be X-15+10 or X+5 year.

so,3(X+5)=2X +10

or, 3X+15=2X+10

or,X=25

age of elder son is 25 years.

age of father is 25*2=50 years.

age of younger son is 25-15 = 10 years.
