Question

If the selling price of a laptop is equal to 6/5 of its cost price. Find the profit percent.

Answer 1

Solution :

Let the cost price of a laptop (c.p)= x

selling price ( s.p ) = 6x/5

profit ( g ) = s.p - c.p

= 6x/5 - x

= ( 6x - 5x )/5

= x/5

Now ,

Profit percentage = ( g × 100 )/c.p

= [ (x/5) × 100 ]/x

= 100/5

= 20

Therefore ,

Profit percentage = 20%

Answer 2

Answer:

20%

Step-by-step explanation:

Let the cost price be x

We are given that the selling price of a laptop is equal to $\frac{6}{5}$ of its cost price.

SP of Laptop = $\frac{6}{5}x$

Profit = SP -CP =  $\frac{6}{5}x-x =\frac{x}{5}$

Profit% =$\frac{Profit}{CP} \times 100$

Profit% =$\frac{\frac{x}{5}}{x} \times 100$

Profit% =$20\%$

Hence the profit percent is 20%
