Question

On what date will Rs. 1950 lent on 5th January, 2011 amount to Rs. 2125.50 at 5 percent per annum simple interest?

Answer 1

P= Rs. 1950
A=Rs. 2125.50
R= 5% p.a.
I= A-P
=Rs. 2125.50 -Rs. 1950
=Rs. 175.50
$T=\frac{100\times I}{P\times R}$
$=\frac{100\times 175.50}{1950\times 5}$
$=\frac{17550}{9750}=\frac{1755}{975}$=$\frac{117}{65}$
$=\frac{9}{5}$ years = $1\frac{4}{5}$ years
1 years 292 days
Jan+Feb+March+April+May+June+July+Aug.+Sept.+Oct.
(31-5)+29+31+30+31+30+31+31+30+23
=292 days
$\therefore$ Required date= 23rd October 2012
