Question

a fruit seller buys oranges at 4 for Rs3 and sells them at 3 for rupees 4 find its profit percent

Answer 1

CP of 4 oranges  = Rs3

CP of 1 orange = 3/4 = 0.75

SP of 3 oranges = Rs4

SP of 1 orange = 4/3 = 1.33

Profit = 1.33 - 0.75 = 0.58

Profit in percent = 0.58/0.75    x  100 =  77.33%

Answer 2

Answer:

The profit percent is 77.8%

Step-by-step explanation:

It has been given that fruit seller buys oranges at 4 for Rs 3.

Therefore, cost price of 1 orange is given by

$CP=\frac{3}{4}$

Now, he sells them at 3 for rupees 4. Thus, selling price of 1 orange is given by

$SP=\frac{4}{3}$

Profit is given by

$Profit=SP-CP\\\\=\frac{4}{3}-\frac{3}{4}\\\\=\frac{7}{12}$

Therefore, profit percentage is given by

$\%Profit=\frac{Profit}{CP}\times100\\\\=\frac{7/12}{3/4}\times100\\\\=\frac{7}{12}\times\frac{4}{3}\times100\\\\=\frac{700}{9}\\\\=77.8\%$
