Question

selling price of a toy car is rupees 540 if the profit made a shopkeeper is 20% what is the cost price of this toy

Answer 1

Selling Price = Rs 540

Find the percentage of the selling price:

Profit = 20%

Selling Price = Cost Price + Profit

Selling Price = 100 + 20 = 120%

Find the cost price:

Selling Price = 120%

Selling Price = Rs 540

120% = Rs 540

1% = 540 ÷ 120 = Rs 4.50

100% = 4.5 x 100 = Rs 450

Answer: The cost price is Rs 450

Answer 2

Given :

selling price = ₹ 540

profit = 20% .


Finding Cost price-


$cost \: price \: = \dfrac{100}{100 + profit} \times sp$


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


$cost \: price \: = \dfrac{100}{120} \times 540$


$cost \: price = \dfrac{54000}{120}$


$cost \: price \: = 450$



$\bold{Answer: Cost \: Price \: = \: Rs \: 450}$
