The bankers gain of a certain sum due 3 years hence at 10% per annum is Rs. 36. What is the present worth ?
Rs. 400
Rs. 300
Rs. 500
Rs. 350
Explanation:
T = 3 years
R = 10%
TD =$\dfrac{BG \times 100}{TR}$= $\dfrac{36 \times 100}{3 \times 10} = 12 \times 10 = Rs.120$
$TD = \dfrac{PW \times TR}{100}$
=>120 = $\dfrac{PW \times 3 \times 10}{100}$
=>1200 = ${PW} \times 3$
$PW = \dfrac{1200}{3}= Rs.400$
