Answer 2

The rate of interest if rupees 25000 amounts to rupees 43200 in 3 years the interest being compounded annually is 20%

Step-by-step explanation:

Principal = Rs.25000

Amount = Rs.43200

Time = 3 years

Rate of interest = r

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

Substitute the values in the formula :

$43200=25000(1+r)^3$

$\frac{43200}{25000}=(1+r)^3$

$\sqrt[3]{\frac{43200}{25000}}=1+r$

$\sqrt[3]{\frac{43200}{25000}}-1=r$

0.2=r

Rate of interest in percent = 20%

Hence  the rate of interest if rupees 25000 amounts to rupees 43200 in 3 years the interest being compounded annually is 20%
