Answer 2

Answer:

The man had a gain of $25\%$ on selling the umbrella.

And the bookseller had a gain of $15\%$ on each book .

Step-by-step explanation:

A man bought an umbrella for $320$ rupees and sold it for $400$ rupees.

So he gained rupees $80$ .

To find the percentage gain , check what percent of $320$ is $80$ .

Let it be $x$ .

So ,

           $320*\frac{x}{100} =80\\\\x=8000/320=25$ .

Therefore the man had a gain of $25\%$ on the umbrella .

And

a bookseller buys a book at Rs. $10$ and sells it for Rs. $11.50$ .

So he had a gain of $1.5$ rupees on each book .

Find out what percent of $10$ is $1.5$ .

Let it be $x$

So,

        $10*\frac{x}{100} =1.5\\\\x=150/10=15$ .

That is, on each book he had a gain of $15\%$ .

Hence the answer.
