If a shopkeeper sold one-third of his goods at a loss of 20%, then at what gain percentage should the remainder be sold to gain 25% on the whole transaction?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 47.5%.
Let total goods = 3 units and CP per unit = 100
Total CP = 3 × 100 = 300
SP of 1 unit = 80
Total SP = 300 × (125/100) = 375
Amount to be recovered = 375 - 80 = 295
SP per unit = 295/2 = 147.5
Gain per unit = 147.5 - 100 = 47.5%
