Rita is twice as old as Rama. Three years ago, she was three
times as old as Rama. How old is Rita now?

• 10 years
  
  If present age of Rita=x & Rama=y, then
  x=2y ---(i) &
  x-3=3*(y-3) or x-3y=-6 ---(ii)
  On solving (i) & (ii), x=12, y=6

• Let Rama's present age = x years
  Then Rita present age = 2x years
  
  Three years ago
  (2x-3) = 3(x-3)
  2x - 3 = 3x - 9
  or x = 6
  
  Rita age = 2x = 2*6 = 12 year.
