A sum of money becomes 8/5 of itself in 5 years at a certain rate of simple interest.Find the rate of interest.​

Answer 1

Answer:

Correct Option: D

Let sum = Rs. P.

Then amount = Rs. (8P/5)

∴ S.I = Rs. (8P/5 - P ) = Rs.(3P/5)

∴ Required rate = (100 x SI) / (P x T)

= [(100 x 3P/5) / (P x 5)]% = 12%
