Ram invested a certain sum in scheme A, which offers simple interest at the rate of 12% p.a. for 3 years. He also invested Rs. 6,000 in scheme B, which offers compound interest (compounded annually) at the rate of 10% p.a. for 2 years. If the interest earned from scheme A is 2/7th of the interest from scheme B, what is the sum invested in scheme A?

• compond interest = 1260
  so 1260*2/7 = 360
  360 = 9P/25
  P = 1000

• For Scheme A, SI = P*N*R/100 = P*12*3/100= 9P/25
  FOR SCHEME B, AMOUNT=P(1+R/100)^N
  = 6000(1+10/100)^2 = 7260
  HENCE COMPOUND INTEREST = (7260-6000)=1260
  ACCORDING TO THE QUESTION, SI of Scheme A = 2/7 th of CI of Scheme B
  9p/25=2/7*1260
  p=1000 This is the required Answer.
