Step-by-step explanation:

I am just providing the shortcut to be used in competitive exams for saving time.

Shortcut to these type of questions

When a person sells two similar items, one at a gain of say “x%”, and the other at a loss of “x%”, then the seller always incurrs a loss.

Loss%= (x/10)^2 %

Here x is common gain or loss percent

Coming to the question

Common gain or loss% = 10%

Using the formula:-

Loss%= (10/10)^2 % = 1%

Thus after transaction the seller will incurr loss of 1%.

Hopefully it helps.
