medium
Hundred oranges are bought at the rate of $Rs.\, 350$ and sold at the rate of $Rs.\, 48$ per dozen. The percentage of profit or loss is
A
$14 \frac{2}{7} \%$ gain
B
$15 \%$ gain
C
$14 \frac{2}{7} \%$ loss
D
$15 \%$ loss
Solution
$C.P. =Rs. 350 / 100=Rs. 3.5 / each$
$S.P. =Rs. 48 / 12=Rs. 4 / each$
$\therefore \quad \frac{ S.P. – C.P. }{ C.P. } \times 100=\frac{4-3.5}{3.5} \times 100=\frac{100}{7}=14 \frac{2}{7} \%$ profit
