Question

2. A shopkeeper bought 300 eggs for 450. Out of these 12 eggs were found broken. He sold
remaining eggs at the rate of 21 per dozen. What is his profit ?
​

Answer 1

Answer:

cost of 100 eggs=250Rs

therefore cost of 1 egg=(250/100)Rs=2.5 Rs

now 10 eggs are broken..

so the number of good eggs=90 pcs

now he sold eggs at the rate of 40 Rs/dozen

therefore....

selling price of 12 pcs eggs=40 Rs

so, selling price of 90 eggs

=[(40/12)×90]Rs

=300 Rs

therefore total profit=(300-250)Rs=50Rs

Answer 2

Answer: ₹54

Given:

$\sf Shopkeeper\;bought\;300\;eggs\;for\;450.\;Out\;of\;these\;12\;were\;broken.$

$\sf He\;sold\;remaining\;eggs\;at\;the\;rate\;of\;21\;per\;dozen.$

To find:

$\sf Profit\:made\:by\:the\:shopkeeper.$

Explanation:

$\sf Given\;that,$

$\sf Cost\:of\:300\:eggs=Rs.450$

$\sf Out\:of\:300\:eggs,\:12\:eggs\:are\:broken.$

$\sf \therefore 300-12=288\:good\:eggs$

$\sf Now,\:the\:shopkeeper\:sold\:288\:eggs\:at\:the\:rate\:of\:Rs.21\:per\:dozen.$

$\sf We\:know\:that,$

$\sf 1\:dozen=12\:units$

$\sf Selling\:price\:of\:12\:eggs=Rs.21$

$\sf \therefore\:selling\:price\:of\:288\:eggs=\dfrac{21}{12}\times288$

                                       $\sf =Rs.504$

$\sf \therefore \:total\:profit=Selling\:price-Cost\:price$

                    $\sf =504-450$

                    $\sf =\boxed{\sf Rs.54}$

Hence, the shopkeeper made a profit of ₹54.
