Q.6) a) A dealer sold two books for Rs. 700 each. On one of the books, he made a profit of 20% and the other at a loss of 20%. Find his profit% or loss% on the whole transaction. *please send me ​

Answer 1

Answer:

Step-by-step explanation:

The Dealer sold 2 books, on one he made a profit of 20%

So lets find the C.P Of the book where the dealer gained profit.

So, lets assume he sold the book at 100Rs. He would have made a profit of 20Rs. Therefore the cost price of the first book would be

$Cost Price = \frac{700 * 80}{100} \\\\\\\Cost Price = 560Rs$

Now for the second book. Since he sold it at a loss of 20% He would have sold it at 80% of the cost price.

$Cost Price 2 \frac{700 * 120}{100} \\\\Cost Price 2 = 840Rs$

Now that we know both the C.P's we can find out the total profit or loss.

So the total C.P = 840Rs + 560Rs

Total C.P = 1400

It has already been told to us that the dealer sold 2 books at a S.P Of Rs 700.

So therefore there is a 0% Profit or Loss. As the Dealer has bought and sold goods for the same price.
