Let the rate of interest be r%.
Simple interest earned on Rs. 25000 in 2 years = 25000 × 0.16 = Rs. 4000
⇒ 4000 = (25000 × r × 2)/100
⇒ r = 8%
∴ Compound interest in 2 years = 25000 × [1 + 8/100]2 - 25000
⇒ 29160 - 25000 = Rs. 4160
Simple interest earned on Rs. 25000 in 2 years = 25000 × 0.16 = Rs. 4000
⇒ 4000 = (25000 × r × 2)/100

∴ Compound interest in 2 years = 25000 × [1 + 8/100]2 - 25000
⇒ 29160 - 25000 = Rs. 4160

1 year rate 16/2=8
8/100=2/25
1st year ka 25000*2/25=2000$
2nd year ka 25000*2/25=2000$*2/25=$160$
2000+2000+160=4160$
8/100=2/25
1st year ka 25000*2/25=2000$
2nd year ka 25000*2/25=2000$*2/25=$160$
2000+2000+160=4160$
