Correct Answer: 7200
Solution:
By using the direct formula of simple interest:\(SI=\frac{PTR}{100}\)
let the principal amount be P, R=12%, T=2, SI=? by solving we will get SI=0.24P
Now use \(Amount=P(1+\frac{R}{100})^n\)
Use R=12% then we will get A= 1.25P
compound interest=A-P =1.25P-P=0.25P
Difference of SI and compound interest is Rs.72
therefore 0.25P-0.24P=72, from this P=Rs. 7200
