The rate of simple interest for first 3 year is 6%, for next 4 years it is 7% and the period beyond 7 years it is 7.5% per annum. If a man invest ₹9400 for 11 years, find the simple interest earned by him?
Answer & explanation
Correct answer: option 3
Total S.I. for first 3 years = 6% × 3 = 18%
Total S.I. for next 4 years = 7% × 4 = 28%
Total S.I. for next 4 years = 7.5% × 4 = 30%
Total S.I. for 11 years = (18 + 28 + 30)% = 76%
S.I. for 11 years = 9400 × 76% = 7144/-
