Question:

By selling 90 pens for ₹80 a man loses 20%. What should be the selling price of 75 pens on 20% profit?

Options:

100

110

120

Correct Answer:

100

Explanation:

CP = \(\frac{80}{90}\) × \(\frac{100}{80}\) = \(\frac{10}{9}\)

SP = \(\frac{10}{9}\) × \(\frac{120}{100}\)

= \(\frac{20 × 5}{15 × 5}\) = \(\frac{100}{75}\)

= 75 pen for Rs. 100
