Question

by selling a saree for Rs 3000 the shopkeeper made a profit of 20%. what was the cost price of the saree ?

Answer 1

Find the percentage of the selling price:

Selling Price = 100 + 20 = 120%

Find the cost price:

120% = Rs 3000

1% = 3000 ÷ 120 = Rs 25

100% = 25 x 100 = Rs 2500

Answer: The cost price of the saree is Rs 2500

Answer 2

Heya,

​​ We know,  

C.P. = { 100/(100 + Profit%) × S.P. }    

Sold Price [S.P.] = ₹ 3,000  

Profit % = 20%  

∴Cost Price [C.P.] of the Saree  

= ₹ { 100/ (100 + 20)  × 3,000 }  

= ₹ { 100/120 × 3,000 }  

= ₹ { 100 × 25 }  

= ₹ 2,500  

Hope it helps !
