Question

What is the simple interest on rs 650 for 14 weeks at 6% per annum ​

Answer 1

10.50

Explanation:

The simple interest (I) is calculated as

I =
`(PRT)/(100)`

where P is the principal ( amount deposited), R is the rate of interest and T the time in years.

note that 14 weeks =
`(14)/(52)` of a year, hence

I =
`(650(6))/(100)` ×
`(14)/(52)`

=
`(650(6)(14))/(100(52))`

=
`(54600)/(5200)` = 10.50

Answer 2

rs 10.5 .

Explanation:

Simple Interest = PRT/100 where P = sum invested, R = the rate per annum, T = the time in years.

14 weeks = 14/52 years so it is:

650* 6 * (14/52) / 100

= rs 10.5.
