The age of a father 10 years ago was thrice the age of his son . Ten years hence, the father's age will be twice that of his son. What is the ratio of their present ages? posted Jul 17, 2015

Father:Son > 7:3
Say father's age= X, Son's Age = Y
10 years ago, X-10 = 3*(y-10) >> 3Y=X+20
10 years from now, X+10 = 2*(Y+10) >> 2Y=X-10
