If x/4 years ago Roger was 14 years old and x/4 years from now he will be 4x years old, how old will he be 6x years from now?
Select: A) 32 B) 39 C) 30 D) 40 E) 28
Assume the current age = a   a - x/4 = 14 (i)   a + x/4 = 4x   Or a = 15x/4 (ii)   Putting the value of a from (ii) in (i)   15x/4 - x/4 = 14   Or 14x/4 = 14 Therefore x = 4 and a = 15   6x years from now, age will be  15 + 6*4=
