Question

cost price of 4 items=selling price of 3 items then find the profit​

Answer 1

We know that if cost price of m articles is equal to the selling price of an articles then there gain percentage or loss percentage will be →

$\frac{m - n}{n} \times 100\%$

Here cost price of 4 items is equal to selling price of 3 items. Then

m = 4

n = 3

Gain percentage = $\frac{4 - 3 }{3}$ × 100

$= > \frac{100}{3}$

Gain percentage = 33.34 percentage.

Answer 2

Given ,

Cost price of 4 items = Selling price of 3 items

According to the question ,

$\to \sf cp × 4 = sp × 3 \\ \\ \sf \to</p><p> \frac{cp}{sp} = \frac{3}{4}$

Therefore , cp = 3 and sp = 4

We know that ,

$\sf \large{ \fbox{ \fbox{Profit \: \% = \frac{(sp- cp)}{cp } \times 100}}}$

$\sf = \frac{(4 - 3)}{3} \times 100 \\ \\ \sf = \frac{1}{3} \times 100 \\ \\ \sf = \frac{100}{3} \\ \\\sf = 33. 3 \: \: \%$

Hence , the required value is 33.3 %
