Question

Selling price of a toy car is Rs 420. If the profit made by shopkeeper is 12%, what is
the cost price of this toy?
​

Answer 1

Answer:

SP is given rupees 240

Profit = 12%

Cp=?

to find cp we use the formula

= SP*100/100+12%

= 420*100/112

=42000/112

= 375

hence, cp is 375

Answer 2

Answer:

Cost price is of 375₹

Step-by-step explanation:

Given that

Selling price of a toy is ₹420

Profit is 12%

To find cost price of the toy

Solution

As we know that

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

profit is

$profit = \frac{12}{100} \times cost \: price$

hence

$420 = cost \: price + \frac{12}{100} \times cost \: price$

now by taking cost price common

$420 = cost \: price(1 + \frac{12}{100} )$

as 12 and 100 both are divisible by 4 hence

$420 = cost \: price(1 + \frac{3}{25} )$

by solving bracket we get

$420 = cost \: price \times \frac{28}{25}$

$cost \: price = 420 \times \frac{25}{28}$

by multiplication we get

$cost \: price = 375rs$

Hence cost price of toy is 375rs.
