Question

find the rate of compound intrest per anum , so that thw amounr on 400 fpr 2 years becomes 441​

Answer 1

Answer:

Using the formula

A= P(1+r/100)^t where t is the time period in years r is the rate, P is the principal and A is the amount so

441=400(1+r/100)^2

441/400=(1+r/100)^2

(21/20)^2=(1+r/100)^2

21/20–1=r/100

1/20=r/100 so

R=5%
