Shopkeeper purchased 510 eggs

Price of one egg = 20/12 ₹

Price of 510 eggs =(20×510) / 12

= 10200/12

= 850 ₹

➡️ 20 % of 850

(20×850)/100= 17000/100

= 170

So

Shopkeeper has to sell

=. 850+ 170= 1020₹


But here 30 eggs have broken

So

Here (510-30)=480 eggs have been

Dozens = 480/12 = 40


Rate per dozen = 1020/40

= 25.5 ₹


Finally your answer ➡️ 25.5₹

Answer 2

Rs. 25.50 per dozen

Total price of 510 Eggs

dozen price = Rs. 20

Price of 510 eggs =510/12×20

= 850

gain is 20%

so gain is =20/100×850

=170

So, SP = 850 + 170

= Rs. 1020

30 eggs are broken = 510 - 30 = 480

so per rup. SP =1020/480

per dozen SP =1020/480×12

= Rs. 25.50
