Question

the ratio of buying price & selling price is 4:5 .what is the percentage of profit?

Answer 1

Hey,

Buying Price : Selling Price = 4:5

Let Buying Price be 4x and Selling Price be 5x.
Since,
Selling Price < Buying Price (I.e. selling price is greater than buying price)
It's Profit.

As we know,
Profit = Selling Price - Buying Price = 5x - 4x = x

Now,
Profit Percentage = (Profit/Buying Price)×100
$profit \: percentage \: = ( \frac{x}{4x} ) \times 100$
$= \frac{1}{4} \times 100$
$= 25\%$

Hence,
Profit Percentage = 25 ℅
