Mehta Traders deposits Rs 80,000 with a bank for 3 years at 7.5% p.a. simple interest. What total interest will the bank pay at maturity?

The interest is Rs 18,000. Simple interest is principal times rate times time divided by 100, so 80,000 x 7.5 x 3 / 100 equals Rs 18,000. The interest is the same every year because it is calculated only on the original principal.

  1. ARs 16,000
  2. BRs 18,000Correct
  3. CRs 20,000
  4. DRs 6,000

Explanation

Simple interest = P x R x T / 100 = 80,000 x 7.5 x 3 / 100 = Rs 18,000. Rs 6,000 is the interest for one year only (the time factor was ignored). Rs 20,000 would arise from using 8.33%, which is not given.
