   • A.680
   • B.980
   • C.800Correct
   • D.620

   SI = P×R×T/100 = 2500×8×4/100 = 800.

5. Question 5Easy

   Find the simple interest on Rs 12000 at 8% per annum for 3 years.

   • A.Rs 2680
   • B.Rs 2880Correct
   • C.Rs 2980
   • D.Rs 3080
   • E.Rs 3180
   Show solution

   Simple interest is principal x rate x time / 100 = 12000 x 8 x 3 / 100. That is 12000 x 24 / 100 = 2880. Simple interest grows by the same amount each year, here 960, so three years is 3 x 960 = 2880.

6. Question 6Easy

   The simple interest on a sum at 8% per annum for 3 years is Rs 960. What is the sum?

   • A.Rs 3500
   • B.Rs 3750
   • C.Rs 4000Correct
   • D.Rs 4250
   • E.Rs 4500
   Show solution

   Simple interest is principal x rate x time. Here 960 = P x 0.08 x 3 = 0.24P, so P = 960 / 0.24 = 4000. Combine the rate and time into a single factor before dividing.
