In how many years will the simple interest on a sum of money be equal to the principle at rate of 12(2/4)% p.a.?
Answer
The correct answer is B: 8 years. SI = Principal when SI/P = 1, i.e., (P×R×T)/(100×P)=1, so T=100/R. Rate = 12.5%, so T=100/12.5=8 years.
- A.7 years
- B.8 years✓ Correct
- C.6 years

SI = Principal when SI/P = 1, i.e., (P×R×T)/(100×P)=1, so T=100/R. Rate = 12.5%, so T=100/12.5=8 years.
