  S.I=1236-1200=36

• IN THIS QUESTION SIMPLE INTEREST IS RS 36 ---- FROM(1236-1200)
  TIME IS 3MONTHS SO WE CAN SAY IN YEARS ITS 1/4 OF A YEAR ---- FROM(12MONTHS/4=3MONTHS)
  SO SIMPLY APPLYING SIMPLE INTEREST FORMULA
  SI=P*R*T/100
  36=1200*R*1/400
  WE GET R=12% PER YEAR SO THE ANSWER IS OPTION C.

• c)12%
  S.I=1236.00-1200.00=36.00
  P=1200.00
  T=3 months=3/12 year
  R=?
  S.I=P*T*R/100
  36=1200*3*R/(12*100)
  R=36*12*100/1200*3
  R=12
