Question

a vendor purchased bananas at rupees 40 per dozen and sold them at 10 for rupees 36 find his gain or loss percent​

Answer 1

Answer:

1 dozen =12 bananas

cost price of 12 bananas = 40

cpst price of 1 banana= 40/12=10/3

sold price of 10 banana= 36

sold price of 1 banana = 36/10=18/5

gain =18/5 - 10/3=4/15

gain %= 4/15×3/10×100=8%
