Simple Interest
6. A sum of money lent at simple interest amounts to Rs 1008 in 2 years and to 1112 in 3 years.Find the sum and the rate of interest.
Principal + Interest for `3` years = `1112`
Principal + Interest for `2` years = `1008`
`=>` Interest for `1` year = `1112 - 1008 = 104`
`=>` Interest for `2` years = `2 * 104 = 208`
Now, Principal + Interest for `2` years = `1008`
`=>` Principal + `208 = 1008`
`=>` Principal = `1008 - 208 = 800`
`SI = (P*R*N)/100`
`R = (SI*100) / (P*N) = ( 208 * 100 ) / ( 800 * 2 ) = 13`
The Sum of money is Rs `800` and the rate of interest is `13` %
