Explanation:

Amount = simple interest + principal
⇒ 9200 = simple interest + 8000
⇒ simple interest = 9200 – 8000 = Rs 1200
if r % be the rate of interest ,
Then from, simple interest = principal × rate% × time /100
1200 = 8000 × r × 3 /100
⇒ r = 5%
2% more interest that is 7% interest
simple interest = 8000 × 7 × 3 /100 = Rs 1680
thus amount he will get is Rs 8000 + Rs 1680 = Rs 9680
