Step-by-step explanation:
The gain percentage is 20%.
Step-by-step explanation:
For Rs. 250, the shopkeeper purchased 100 eggs and among them, 10 eggs were broken.
Then the cost of purchase (CP) = 250 Rs.
So, the remaining number of eggs is (100 - 10) = 90.
If he sold the renaming eggs at the rate of rupees 40 per dozen, then the sale price (SP) of the eggs will be \frac{40 \times 90}{12} = 300
12
40×90
=300 Rs.
Since the cost of the purchase is less than the sale price, so, he makes a gain.
So, the gain percentage is \frac{300 - 250}{250} \times 100\% = 20\%
250
300−250
×100%=20% . (Answer)
