Answer 2

The given question is At what rate of interest per anum will 2000 naira gain an interest of 640 naira in 4 years

Here, in this question we have to find the rate of interest.

As we know the formula for rate of interest is

$\frac{simple \: interest \: \times 100}{principal \times time \: taken}$

so, here SI = 640

P=2000

T=4

$\frac{640 \times 100}{2000 \times 4}$

$\frac{64000}{8000} = 8$

The rate of interest is 8% per annum
