Question

invested 5000 at 10% per annum compound interest. After n years, I received 1655 more. Find tns value of n.​

Answer 1

Answer:

Time is 3 years

Step-by-step explanation:

We have

Principal, P = Rs 5000

Rate, R = 10% per annum

Compound Interest, CI = Rs 1655

Thus, Amount is calculated as

Amount = Principal + Compound Interest

A = Rs 5000 + Rs 1655

A = Rs 6655

Let number of years be nn years.

Using the formula for compound interest, we have

A=P(1+R/100)T

6655=5000(1+10/100)n

6655/5000=(1+1/10)n

1331/1000=(11/10)n

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

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

On comparing, we get

n = 3 years

Thus, time is 3 years
