Answer 1

Answer:

Step-by-step explanation:

SP = 540, Profit = 20%

SP = CP + Profit

Cost Price = Selling Price × 100/100 + Profit %

= 540 × 100/100 + 20

= 54000/120

= ₹450

Answer 2

Answer:

Cost price is of 450₹

Step-by-step explanation:

Given that

Selling price of a toy is ₹540

Profit is 20%

To find cost price of the toy

Solution

As we know that

$selling \: price = cost \: price + profit$

profit is

$profit = \frac{20}{100} \times cost \: price$

hence

$540 = cost \: price + \frac{20}{100} \times cost \: price$

now by taking cost price common

$540 = cost \: price(1 + \frac{20}{100} )$

as 20 and 100 both are divisible buly 20 hence

$540 = cost \: price(1 + \frac{1}{5} )$

by solving bracket we get

$540 = cost \: price \times \frac{6}{5}$

$cost \: price = 540 \times \frac{5}{6}$

by multiplication we get

$cost \: price = 450rs$

Hence cost price of toy is 450rs.
