Some toffees are bought at the rate of 11 for ₹10 and the same numbers at the rate of 5 for ₹6, If the whole lot is sold at one rupee per toffee, then the gain/loss percent, correct to one decimal place, on the whole transaction is:
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 5.2% loss.
Let the number of toffees bought at each rate = 55 (LCM of 11 and 5).
Buy 55 toffees at 11 , so for ₹10 → ₹50
Buy 55 toffees at 5, so for ₹6 → ₹66
Total cost = ₹50 + ₹66 = ₹116
Total toffees = 110, sold at ₹1 each ,so SP = ₹110
Loss = 116 − 110 = ₹6
Loss% = (6/116) × 100 ≈ 5.2%
