Question

in how many years rupees 4000 amount to Rupees 5324 at 10% compound interest​

Answer 1

Answer:

Step-by-step explanation:

↓↓↓

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
