Rohit was 4 times as old as his son 8 years ago. After 8 years, Rohit will be twice as old as his son. What are their present ages?
Choose the correct choice from the following
A) 16 and 40 years	B) 13 and 37 years	C) 10 and 34 years	D) 11 and 35 years	E) 20 and 44 years
Let son's age 8 years ago be x years.   Then, Rohit's age 8 years ago = 4x years.   Son's age after 8 years = (x + 8) + 8 = (x + 16) years.   Rohit's age after 8 years = (4x + 8) + 8 = (4x+ 16) years.   2 (x + 16) = 4x + 16   2x = 16   x = 8.   Hence, son's 'present age = (x + 8) = 16 years.   Rohit's present age = (4x + 8) = 40 years.   16 and 40 yearsnswer is 16 and 40 years.
