Feedback Given
Principal : 2400
Rate of interest : 10
Number of months : 7
Simple interest = ( P * N * R ) / 100
Simple Interest for 1 year
= (2400 x 1 x 10) / 100
= ( 24000) / 100
= Rs 240
Simple Interest for 1 year = 240.
Simple interest for 7 months
= (7/12) x Simple Interest for 1 year
= (7/12) x 240
