प्रश्न

Find the S.I. and amount on: 600 from July 12 to Dec. 5 at 10% p.a.

योग

उत्तर

P = Rs. 600, R = 10% p.a.

T = July 12 to Dec. 5

July = 19 Days
Aug. = 31 Days
Sep. = 30 Days
Oct. = 31 Days
Nov. = 30 Days
Dec. = 05 Days
Total 146 Days

`= 146/365` years = `2/5` years

∴ S.I. = `"P.R.T"/100 = (600 xx 10 xx 2)/(100 xx 5)` = Rs. 24

∴ Amount = P + S.I.

= Rs. 600 + Rs. 24

= Rs. 624
