Find the simple interest on (a) Rs. 2500 at 15% per annum for 2 years.

1.	Find the simple interest on (a) Rs. 2500 at 15% per annum for 2 years. (b) Rs. 3000 at `17 (1)/(3)%` per annum for `1(1)/(2)` years.
Answer» (a) Given, Principal (P)=Rs. 2500, Rate (R )=15% and Time period (T)=2years `therefore` Simple interest `=(PTR)/(100)=(2500xx2xx15)/(100)=750` Hence, simple interest = Rs. 750 (b) Given, Principal (P)=Rs. 3000 Rate (R )`=17(1)/(3)%=(52)/(3)%` per annum And time period(T) `=1(1)/(2)` years `therefore` Simple interest `=(PTR)/(100)=(3000xx(3)/(2)xx(52)/(3))/(100)=780` Hence, simple interest =Rs. 780
