Question

if rupees 10000 amounts to rupees 12100 in a few years find the duration of investment if the rate of interest is 10 p.c.p.a compounded annually

Answer 1

The duration of investment if the rate of interest is 10 p.c.p.a compounded annually is 2 years

Step-by-step explanation:

Principal = 10000

Amount = 12100

Rate of interest = r = 10% = 0.1

Formula : $A=P(1+r)^t$

Substitute the values in the formula :

$12100=10000(1+0.1)^t$

$\frac{12100}{10000}=1.1^t$

$1.21=1.1^t$

$1.1^2=1.1^t$

t=2

Hence the duration of investment if the rate of interest is 10 p.c.p.a compounded annually is 2 years
