Find the simple interest on Rs. 3000 at $6\frac{1}{4}$% per annum for the period from

4th Feb., 2005 to 18th April, 2005.

Correct Answer : A.

         Time = (24+31+18)days = 73 days = 73/365 years = 1/5 years.

         P = Rs.3000 and R = 6 ¼ %p.a = 25/4%p.a

         S.I. = Rs.(3,000*(25/4)*(1/5)*(1/100))= Rs.37.50.
