- Question
- In a certain time, a sum becomes 4 times at the rate of 5% per annum. At what rate of simple interest, the same sum becomes 8 times in the same duration?
Options- A. 122/3 %
- B. 113/5 %
- C. 112/3 %
- D. 123/5 %
- Correct Answer
- 112/3 %
ExplanationLet the sum be p
Then, for R = 5%
SI = (4p - p) = 3p
? 3p = (P x 5 x T)/100 = PT/20
? T = 60 yr
Again, for another rate (R)
SI = (8P - P) = 7P
? 7P = (P x R x 60)/100
? R = (7 x 100)/60 = 35/3%
= 112/3 % - 1. Find the odd word / letter / number from the given alternative
