Question 21

The sum which will earn a simple interest of Rs. 126 in 2 yr at 14 % per annum, is
(a) Rs. 394
(b) Rs. 395
(c) Rs. 450
(d) Rs. 540

Answer 1

Given, I = Rs. 126, R = 14 % and T = 2 yr
$\therefore I=\frac{P\times R\times T}{100}\Rightarrow 126=\frac{P\times 14\times 2}{100}\Rightarrow 126\times 100=P\times 14\times 2\Rightarrow P=\frac{12600}{14\times 2}\Rightarrow P=Rs.450$
