Q. The S.I accrued on a sum of certain principal is Rs 7200 in Six years at the rate of 12 percent per annum. What would be the C.I accrued on that principal at the rate of 5 percent per annum in 2 years?

option.
1) Rs 1020
2) Rs 1055
3) Rs 1050
4) Rs 1025
5) None of these

• 1025
  
  principal = 7200*100/(6*12) = 10000 Rs.
  CI on Rs 10000 at the rate of 5 percent per annum in 2 years = 10000*(1+5/100)^2 = 10000*(21/20)*(21/20) -10000 = 11025-10000= Rs.1025

• Principal = (7200*100)/(12*6)=10000
  
  Now, CI=(10000(1+5/100)^2)-10000
  =11025-10000=1025
  
  so, 4 is the right answer.

• pricipal is=7200*100/(6*12)=10000
  so compound interest=10000*(1.05)^2-10000=1025

• pricipal is=7200*100/(6*12)=10000
  so compound interest=10000*(1.05)^2-10000=1025
