The bankers gain on a sum due 6 years hence at 12% per annum is Rs. 540. What is the bankers discount?
1240
1120
1190
1290
Explanation:
$TD = \dfrac{BG \times 100} {TR}$
$=\dfrac{540 \times 100}{6 \times 12}= \dfrac{90 \times 100}{12}$
$= \dfrac{15 \times 100}{2} = Rs.750$
BG = BD - TD
=> 540 = BD - 750
=> BD = 540 + 750 = 1290
