Question

the interest on a sum of money at the end of 5/2 years is 4/5 of the sum what is the rate percent

Answer 1

Answer:

32% p.a.

Step-by-step explanation:

Let amount be P, and rate be R%.

In 5/2 years, the interest is: 5PR/200. (Using I = PRT/100)

Given: I = 4P/5

So, 5PR/200 = 4P/5

=> R = 32.

Rate of interest is 32% per year.
