• let no be x
  on dividing by 84 it gives remainder 57
  since every no divisible by 84 must be divisible by 12
  thus number x on dividing by 12 will be like 12*y + 57 i.e. 12*y+ 12* 4 + 9
  therefore we got 9 as remainder on dividing by 12

• let x be the number
  x=84Q+57
  (84Q+57)%12=R
  let us assume Q=1
  (84+57)%12=R
  (141)%12=R
  Remainder=9
