In how many years will the simple interest on a sum of money be equal to the principal at the rate of 2(6/7)% per annum?
Answer
The correct answer is C: 35 years. For SI to equal principal, SI = P. So P × r × t / 100 = P, meaning r × t = 100.
- A.33 years
- B.37 years
- C.35 years✓ Correct
- D.34 years
For SI to equal principal, SI = P. So P × r × t / 100 = P, meaning r × t = 100. Rate = 2(6/7)% = 20/7%. So t = 100 ÷ (20/7) = 100 × 7/20 = 35 years.
