Question

A vendor bought oranges at 20 for rupees 125 and sold them at rupees 90 per dozen . Find his gain or loss percent

Answer 1

Purchase price for 20 oranges =125; therefore price of each orange 125/20=6.25

Selling price of 1dozen(12pcs) is 90; selling price of 1 orange= 90/12=7.50

Profit per orange is 7.5-6.25=1.25

The gain percentage is Gain/purchase price*100= 1.25/6.25*100=20%

Answer 2

Find the cost price of 1 orange:

Cost Price of 20 oranges = Rs 125

Cost Price of 1 orange = 125 ÷ 20 = Rs 6.25

Find the selling price of 1 orange:

Selling Price of 12 oranges = Rs 90

Selling Price of 1 orange = 90 ÷ 12 = Rs 7.50

.

Find the gain percentage:

Gain = 7.50 - 6.25 = Rs 1.25

Gain percentage = 1.25/6.25 x 100 = 20%

Answer: His gain is 20%
