Answer 2

Answer:

1%

Step-by-step explanation:

300 is the cost price. If you found profit and loss % same on cost price then no need to do math you just remember there will be no profit or loss. But if there is gain or loss percentage on selling price then you have to remember a formula

(+-x)+(+-y)+(+-xy/100)

Here + for gain and - for loss

Suppose in this question gain and loss after selling

Then +10+-10+-100/100

= -1% so there will be a loss of 1%
