The interest on a certain deposit at 4.5% p.a. is Rs. 202.50 in one year. How much will the additional interest in one year be on the same deposit at 5% p.a.?	Choose the correct choice from the following
A) Rs. 20.25
B) Rs. 22.50
C) Rs. 25
D) Rs. 42.75
E) None
Solution   S.I. = Rs. 202.50, R = 4.5% ,T = 1 year.   principal = Rs. (100x202.50/4.5x1)= Rs. 4500.   Now,P = Rs. 4500,R = 5% ,T = 1 year.   S.I. = Rs.(4500x5x1/1000 = Rs. 225.   ∴ Difference in interest = Rs. (225 - 202.50)= Rs. 22.50.   Answer Rs. 22.50
