Tick (✓) the correct answer:

Bananas are bought at 3 for Rs 2 and sold at 2 for Rs 3. The gain per cent is

(a) 25%

(b) 50%

(c) 75%

(d) 125%


(d) 125%

Cost price of a banana $=\mathrm{Rs} \frac{2}{3}$

Selling price of a banana $=\mathrm{Rs} \frac{3}{2}$

Now, profit $=\mathrm{Rs}\left(\frac{3}{2}-\frac{2}{3}\right)=\mathrm{Rs} \frac{9-4}{6}=\mathrm{Rs} \frac{5}{6}$

$\therefore$ Gain percentage $=\frac{\text { gain }}{\mathrm{CP}} \times 100$

$=\frac{\left(\frac{5}{6}\right)}{\left(\frac{2}{3}\right)} \times 100$

$=\frac{5}{6} \times \frac{3}{2} \times 100$

$=\frac{5}{4} \times 100$

$=5 \times 25$

$=125 \%$
