A man bought two bicycles for ₹3,000 each. If he sells one bicycle at a profit of 10%, then for how much percentage profit should he sell the other bicycle so that he makes a profit of 20% on the whole?
Answer & explanation
Correct answer: option 3
CP SP
Profit of 10% on first = 10 11
Profit of x on second = 10 _ (CP is same)
————————————
Overall profit 20% = 20 24
So, SP of second = 24 - 11 = 13
Profit = 13 - 10 = 3
So, \(\frac{3 × 100}{10}\) = 30%
