​

Answer 1

Step-by-step explanation:

Let us take the selling price (S.P.) of 10 pens to be Rs. x.

Now, from this we can say that the S.P. of 1 article is

=Rs. x10=Rs. x10

Now, as given in the question, we know that the cost price(C.P.) of 14 pens is also Rs. x.

So, from this, we can get the C.P. of 1 article is

=Rs. x14=Rs. x14

Now, the profit made by selling 10 pens can be calculated as follows

Profit=selling price of 10 pens -cost price of 10 pens

 Profit=x-10 times the cost price of 1 pens

(As assumed at the start of the question)

=x−10×x14=4x10=2x5=x−10×x14=4x10=2x5

Hence, this is the profit that is experienced.

Now, for the profit percent, we can use the formula that is given in the hint as follows

⇒profit%=profitC.P.×100⇒profit%=2x510×x14×100⇒profit%
