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