# What will Rs 500 amounts to in 10 years after its deposit in a bank which pays annual interest rate of 10% compounded annually?

**Solution:**

The amount deposited in the bank is ₹ 500.

At the end of the first year,

the amount in ₹ = 500 (1 + 1/10)

= 500 (1.1)

At the end of second year, amount in ₹

= 500 (1.1)(1.1)

At the end of third year, amount in ₹

= 500 (1.1)(1.1)(1.1) and so on…

Therefore, at the end of 10 years, amount in ₹

= 500(1.1)(1.1)(1.1) .... 10 times

= 500(1.1)^{10}
