Simple Interest
9. A sum was put at simple interest at a certain rate for 2 years. Had it been put at 3 % highere rate, it whould have fetched Rs. 300 more. Find the sum.
Let sum = Rs. `X` and original rate = `R` %
Then,
`(X * ( R + 3 ) * 2)/100 - (X * R * 2)/100 = 300`
`2 R X + 6 X - 2 R X = 300 * 100`
`6 X = 300 * 100`
`X = 5000`
The sum is Rs. `5000` .
