a fruitseller buys oranges at 4 for Rs.3 and sells them at 3 forRs. 4.find the gain percent.
Cost price of 4 oranges = Rs. 3
Cost price of each orange = 3/4 = Rs. 0.75
Selling price of 3 oranges = Rs. 4
Selling price of each orange = 4/3 = Rs.1.33
So gain = 1.33-0.75=0.58
Gain percentage = gain/cost price * 100 = 0.58/0.75 * 100 = 77.33%
