Question

on selling 36 oranges a vendor loses the selling price of 4 oranges. Find his loss percent.

Answer 1

let selling price of 1 orange = x
SP of 36 oranges = 36x
loss = 4x
CP = 36x+4x = 40x

loss % = 4x/40x * 100 = 10%

Answer 2

Answer
R = 36p
R = revenue
p = selling price per orange
C = 36c
C = cost of oranges
c = cost per orange
C - R = 4p
36c - 36p = 4p
36c = 40p
p = 36c/40 = 9/10c

The vendor is selling the oranges at 90% of cost. The vendor is losing 10% on every orange sold.
