The age of father 10 years ago was thrice the age of his son. Ten years hence, father's age will be twice that of his son. The ratio of their present ages is:
Answer: Option
Explanation:
Let the ages of father and son 10 years ago be 3x and x years respectively.
Then, (3x + 10) + 10 = 2[(x + 10) + 10]
3x + 20 = 2x + 40
x = 20.
Required ratio = (3x + 10) : (x + 10) = 70 : 30 = 7 : 3.

Guys, can anyone tell me about this problem?
Sushil was thrice as old as Snehal 6 years back. Sushil will be5/3 times as old as Snehal 6 years hence. How old is Snehal today?
Why can't we take Snehal Current age be x?
6yrs ago be x-6.
Sushil ag 6ysr ago be 3(x-6) of Snegal age.
6 yrs hence from current age Sushil be,
3(x-6)+6+6= 5/3(x)+6.
Is is the correct way?
