A seller bought three different types of mobile covers C1, C2, and C3. The ratio of their selling prices was 3 : 4 : 5. He made a profit of 25% on C1, 10% on C2, but incurred a loss of 20% on C3. What is his approximate percentage gain or loss in the entire transaction?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Loss of 2.33%.
SP ratio = 3 : 4 : 5
Let SPs be ₹300, ₹400, ₹500
C1: profit 25%
CP1 = = ₹240
C2: profit 10%
CP2 = ≈ ₹363.64
C3: loss 20%
CP3 = = ₹625
Total CP = 240 + 363.64 + 625 = ₹1228.64
Total SP = 300 + 400 + 500 = ₹1200
Loss = 1228.64 − 1200 = ₹28.64
Loss % = × 100 = 2.33% loss
