Question

Find the S.I. and amount on: Rs. 850 from 10th March to 3rd August at `2 1/2` % p.a.

Answer 1

P = Rs. 850, R = `2 1/2% = 5/2 %` p.a.

T = 10th march to 3rd Aug.

March	= 21 Days
April	= 30 Days
May	= 31 Days
June	= 30 Days
July	= 31 Days
Aug.	= 03 Days
Total	146 Days

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

∴ S.I. = `"P.R.T"/100 = (850 xx 5 xx 2)/(100 xx 2 xx 5) =  850/100`

∴ Amount = P + S.I.

= Rs. 850 + Rs. 8.50

= Rs. 858.50
