Answer 1

Here,
Shopkeeper's Cost price =
$300 \times 80 \: paise$
$= 300 \times \frac{80}{100} \: rupees$
$= 300 \times \frac{4}{5}$
$= \frac{1200}{5}$
$= 240$
Therefore, C.P. = 240 rupees

His Selling price =

$(300 - 30) \times 1rupee$
Since 30 eggs were broken

$= 270 \times 1$
$= 270$
Therefore S.P. = 270 rupees

Then,
Shopkeeper's S.P. > his C.P
So, he has a gain

Gain = S.P. - C.P.

$= 270 - 240$
$= 30$
Hence his gain = 30 Rupees

Now, gain % = gain / C.P. × 100

$= \frac{30}{240} \times 100$
$= \frac{1}{8} \times 100$
$= \frac{100}{8}$
$= 12.5\%$
Hence, the shopkeeper has a gain of 12.5%

That's your answer.

Hope it'll help.. :-D
