Question

the interest on a sum of money at the end of 2 1/2 years is 4/5 of the sum what is the rath percent ??​

Answer 1

Step-by-step explanation:

Let the sum (P) = Rs. 100

∴ S.I. = Rs. 100 × (4/5) = Rs. 80

Period (T) = 2. 1/2 = 5/2 Years.

∴ Rate = S.I. × 100/P × T = 80 × 100 × 2/100 × 5 = 32% p.a.

THIS IS CORRECT ANSWER......
