Question

The simple interest on a certain sum of money for 2(1/2) years at 12% per annum is Rs.40

​

Answer 1

Explanation:

`si = p * (r)/(100) * t`

`si = 40 * (12)/(100) * (5)/(2)`

`si = (40 * 12 * 5)/(100 * 2)`

`si = (4 * 12 * 5)/(10 * 2)`

`si = (4 * 12 )/(5* 2)`

`si = (2 * 12)/(5)`

`si = (24)/(5)`

`si = 4.8`
