Question

find the amount of rs 12000 after 2 years compounded annually the rate of interest being 5 % per annum for first year and 6 % per annum during the second year
​

Answer 1

Here, P = $12000, p = 5 % p.a. and q = 6 % p.a.

Using the formula A = {P × (1 + P/100) × (1 + q/100)}

amount after 2 years = $ {12000 × (1 + 5/100) × (1 + 6/100)}

= $ (12000 × 21/20 × 53/50)

=$ 13356

Thus, amount after 2 years = $ 13356
