Question:
Tick (✓) the correct answer:
Rajan buys a toy for Rs 75 and sells it for Rs 100. His gain per cent is
(a) 25%
(b) 20%
(c) $33 \frac{1}{3} \%$
(d) $37 \frac{1}{2} \%$
Solution:
(c) $33 \frac{1}{3} \%$
$\mathrm{SP}=\mathrm{Rs} 100$
Gain $=\mathrm{Rs}(100-75)$
= RS 25
$\therefore$ Gain percentage $=\left(\frac{\text { gain }}{\mathrm{CP}} \times 100\right) \%$
$\quad=\left(\frac{25}{75} \times 100\right) \%$
$\quad=33 \frac{1}{3} \%$
