Correct Answer: 5. (4)
Solution: 5. (4) From statement A,
Let $\mathrm{CP}$ of 1 printer $=₹ 1$
$\therefore \quad \mathrm{CP}$ of 5 printers $=₹ 5$
and SP of 5 printers $=₹ 6$
$\therefore$ Gain $%=\frac{1}{5} \times 100=20 %$
$\therefore \quad \mathrm{CP}=\frac{100}{120} \times 3000=₹ 2500$
$\Rightarrow$ Gain $=₹(3000-2500)$
$=₹ 500$
From statement B, we can also find the answer.
