A banker paid Rs.5767.20 for a bill of Rs.5840, drawn of Apr 4 at 6 months. If the rate of interest was 7%, what was the day on which the bill was discounted?
F = Rs.5840
R = 7%
BD = 5840 - 5767.20 = Rs.72.8
BD =$\dfrac{FTR}{100}$=>72.8 = $\dfrac{5840 \times T \times 7}{100}$
=>T = $\dfrac{72.8 \times 100}{7 \times 5840} $= $\dfrac{10.4 \times 100}{5840}$
=$\dfrac{1040}{5840}$ = $\dfrac{104}{584}$= $\dfrac{13}{73}$ years
=$ \dfrac{13 \times 365}{73}$days= 65days
=> Unexpired Time = 65 days
Given that Date of Draw of the bill = 4th April at 6 months
=> Nominally Due Date = 4th October
=> Legally Due Date = [4thOctober + 3 days] = 7th October
Hence, The date on which the bill was discounted
= [7th October - 65 days]
= [7th October - 7 days in October - 30 days in September - 28 days in August]
= 3rd August
