Question

a dealer suffered a loss of 10% by selling an article for rupees 2520 at what price should he sell it to make a profit of 4 %

Answer 1

SP = CP[100÷(100-loss%)]
=>2520 = CP [100÷(100-10)]
=>2520= CP(100÷90)
=>2520×9/10=CP
=> CP = Rs. 2268
Now,
SP = CP[(100+profit%)÷100]
= 2268 [(100+4)÷100]
= (2268×104) ÷ 100
=Rs. 2358.72
Hence he has to sell at Rs. 2358.72 to make a 4% profit.

Answer 2

Answer:

Rs. 75 or 25

Step-by-step explanation:

Let the cost price be Rs. x

Selling price = Rs. 18.75

Loss= Cost price − Selling price

⇒

100

x

×x=x−18.75

⇒

100

x

=x−18.75

⇒x

=100x−1875

⇒ x

−100x+1875=0

⇒(x−75)(x−25)=0

⇒ x=75 or x=25

Therefore, the cost price is Rs. 75 or Rs. 25.
