  12 year old Manick is three times as old as his brother Rahul who must be 4 years old.

• If 12 years manick=3(x i.e., rahul's age) then x=4
  if rahul=8(4+4) then manick=12+4=16
  so ANS: 16 YEARS..

• manick age=12, then rahul age=4(ratio of age of manick rahul is 3:1)
  after 4 years ,
  manick age=16 and rahul=8(ratio is 2:1)
  hence manick age=16
