Question

in how many years will Rs 4000 amount to Rs 5324 at 10% compound interest?

Answer 1

Answer:

Step-by-step explanation:

Hey mate here is your answer:

_____________________________________

CI=p {(1+r)^n-1} ,

5324-4000=4000 {(1+10/100)^n}-4000 ,

5324=4000 (1+1/10)^n ,

5324/4000=(11/10)^n ,

1331/1000=(11/10)^n ,

(11/10)^3=(11/10)^n ,

n=3 ,

Hence 3 years is the answer.
