A shopkeeper bought toffees at the rate of 6 for ₹4 and sold them at the rate of 4 for ₹6. His gain percentage is
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 125%
The rates are for different numbers of toffees, so compare the cost price and selling price of the same number of toffees; the LCM of 6 and 4, that is 12, avoids fractions.
Cost of 12 toffees (6 for ₹4): \(2\times4=\) ₹8
Selling price of 12 toffees (4 for ₹6): \(3\times6=\) ₹18
Gain \(=18-8=\) ₹10
Gain% \(=\frac{10}{8}\times100=\) 125%
