STEP BY STEP EXPLANATION :

cost of dozen eggs=6

cost of 50 dozen eggs=6×40=240

Total number of eggs =40×12=480

Number of eggs left after removing the broken ones =240−40=200

SP of 1 egg=60 paise

So, SP of 200 eggs=200×60=12000 paise=Rs.12000/100=Rs.120

Loss=CP−SP=Rs.(240-120)=Rs.120

Loss%=(Loss/CP)×100=(120/240)×100= 50%
