He spent 4x12x4 = 192 rupees. But now there are only 41 eggs. To gain 10 percent on the whole, he has to sell these 41 eggs on 192 + 19.2 = Rs.211.2. So each egg shall cost Rs.211.2/41 which is around Rs.5.15

Dozen=12
price of each egg=Rs 4
Total price=4*12*4
=Rs 192
Seven were broken=4*7
=21
192-21=171
To gain 10% profit he should sell them at rate of
192*110/100=211.2
12*4=Total eggs=48
Present no. of eggs=48-7=41
To gain Rs 211.2 he should sell each egg at rate of 211.2/41=Rs 5.15
Hope this helps!
