A man bought pens at the rate of 12 for Rs. 8 and sold them at the rate of 4 for Rs. 6. His gain % in a transaction is?
Answer & explanation
Correct answer: option 3
Price Qty.
Buy: 8 12 ..........(i)
Sell 6 4 ..........(ii)
(i) × 1 and (ii) × 3, (to make qty equal)
Price Qty.
Buy: 8 12
Sell 18 12
Cost price of 12 = Rs.8
Selling price of 12 = Rs.18
Profit = 18 - 8 = 10
Profit percent = \(\frac{10}{8}\)× 100 = \(\frac{5}{4}\)× 100 = 125%
