By selling 18 oranges for a rupee a man losses 20%. How many oranges should he sell for Rs.1 to earn 20% profit?
Answer & explanation
Correct answer: option 2
CP = \(\frac{1}{18}\) × \(\frac{100}{80}\) = \(\frac{5}{72}\)
SP = \(\frac{5}{72}\) × \(\frac{120}{100}\) = \(\frac{1}{12}\)
Therefore, he should sell 12 oranges for Rs. 1.
