Here, mathrmP= Rs. 4800 ; S.I. = Rs. 2400 ; Time = 3 years Let ' R ' be the rate of interest p.a Then, , mathrmR=(100 × mathrmS . mathrmI ./ mathrmP × mathrmT) =(100 × 2400/4800 × 3) =(50/3) %=16 (2/3) %

Q. At what rate of interest will Rs. 4800 earn an interest of Rs. 2400 in 3 years?

$18 \frac{1}{2} %$

$16 \frac{2}{3} %$

$6 \frac{1}{4} %$

None

Here, $P =$ Rs. 4800 ; S.I. $=$ Rs. 2400 ; Time $=$ 3 years
Let ' $R$ ' be the rate of interest p.a
Then, $, R = \frac{100 \times S . I .}{P \times T} = \frac{100 \times 2400}{4800 \times 3}$
$= \frac{50}{3} % = 16 \frac{2}{3} %$
