Correct Answer: 4600
Solution:
By using the direct formula of simple interest:\(SI=\frac{PTR}{100}\)
let the principal amount be P, R=10%, T=2, SI=? by solving we will get SI=0.20P
Now use \(Amount=P(1+\frac{R}{100})^n\)
Use R=12% then we will get A
compound interest=A-P =A-P=0.21P
Difference of SI and compound interest is Rs.72
therefore 0.21P-0.20P=46, from this P=Rs. 4600
