Find the simple interest on (a) Rs. 25...

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.

Text Solution

Verified by Experts

(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
