Question

At what time rs4000 given an interest of rs 500 at 5% p.a.

Answer 1

Step-by-step explanation:

$500 = \frac{4000 \times 5 \times x}{100} = \\ 40 \times 5 \times x \\ 40 \times 5 \times x = 500 \\ 200 \times x = 500 \\ x = \frac{500}{200} = \frac{5}{2} = 2.5 \\ x = 2.5yrs$

Therefore it would take 2.5 years
