Question

Find the S.I. and amount on Rs. 620 for 4 months at 8 p. per rupee per month.

Answer 1

P = Rs. 620, R = 8 p. per rupee per month = 8% p.m..

T = 4 months

∴ S.I. = `("P.R.T")/100 = (620 xx 8 xx 4)/(100)` = Rs. `19840/100` = Rs. 198.40

and amount = P + S.I.

= Rs. 620 + Rs. 198.40 = Rs. 818.40
