उत्तर
The extra interest earned= C.I. - S.I. =Rs (8,640 - 8,000) =Rs 640.
The interest for the first year = S. I. for 2 years / 2 = Rs `8000/2` = Rs 4000
Therefore, the rate of interest = `640/4000 xx 100 = 16 %`
Now ,
S.I. = `("P" xx "r" xx "t")/100`
`=> "Rs" 8000 = ("P" xx 16 xx 2)/100`
`=> P = Rs (8000 xx 100)/32`
`=> P = "Rs" 25000`
The rate of interest was 16°/o and the original sum was Rs 25,000.
