Find the interest on a sum of Rs. 8250 for 3 years at a rate of 8% per annum.
Given :
Principal $= Rs. 8250$
Time $= 3 years$
Rate of interest $= 8$%
To do:
We have to find interest.
Solution :
We know that,
Simple interest (SI) $= \frac{PTR}{100}$
where P is the principal, T is time and R is the rate of interest.
Therefore,
$SI = Rs. 8250\times 3\times \frac{8}{100}$
$= Rs. 825\times 3\times \frac{8}{10}$
$= Rs. 165\times 3\times \frac{8}{2}$
$= Rs. 165\times 3\times 4$
$= Rs. 165\times 12$
$= Rs. 1980$
Interest on a sum of Rs. 8250 for 3 years at the rate of 8% per annum is Rs. 1980.
