Hi ...
Solution :-
The difference between the compound interest and the simple interest for 2 years is the interest on the first years's interest.
First year's simple interest = Rs. 720/2 = Rs. 360
Compound Interest - Simple Interest = Rs. 756 - Rs. 720
= Rs. 36
Therefore, Interest on Rs. 360 for 1 year = Rs. 36
Interest on Rs. 100 for 1 year = (36*100)/360
= Rs. 10
Therefore, rate of interest = (10*100)/100 = 10 %
