Question

if the simple interest on a sum at 4% per annum for 2 years is rupees 80 then the compound interest on the same sum for the same period is what​

Answer 1

Hey bro

SI= 80rs

T= 2 years

Rate = 4% per year

P = SI×100/R×T

= 80×100/4×2

= 1000 rs

Compound interest

A= 1000× 104/100×104/100

= 1081.6

CI = 1081.6-1000

= 81.6 rs
