I hope this helps you.

Answer 2

Answer: Rs. 3121.6

Step-by-step explanation:

Given

Principle = Rs 25000

The interest is compounded annually

Therefore

Rate ; R= $\dfrac{8}{2} = 4\%$

Time : t = $1\dfrac{1}{2} \times 2 = 3 years$

Now as we know

$A=P(1+\dfrac{R}{100} )^t= 25000(1+\dfrac{4}{100} )^3\\\\=25000\times \dfrac{104}{100} \times \dfrac{104}{100} \times \dfrac{104}{100} = Rs. 28121.6$

C.I. = amount - principle =28121.6- 25000= Rs. 3121.6

Hence , the compound interest is  Rs. 3121.6
