Question

at what rate percent per annum will rs 64 amount to rs 125 in 3 years a compound interest, interest being compounded annually? please do it. i will mark you as brainliest.

Answer 1

Here the principle is 64
Interest is 125
Compound interest = principle *{1+r/100}power n
Where r=rate of interest and n=number of years
Therefore
125 = 64 *{1+r/100} power 3
125/64 = {1+r/100}power3
Taking cube root both sides
5/4 = 1+r/100
5/4-1 = r/100
1/4 = r/100
Taking 100 the other side
1/4*100 = r
Therefore r=100/4
R=25
