cost price=20 per dozen
selling price=10 for 25eggs
find gain or loss%
Answer provided by our tutors
let
if cost is 20 per dozen then 20/10 = 2 is the cost price for one: CP = 2
if selling price is 10 for 25 eggs then 10/25 = 0.4 is the selling price for 1 egg SP = 0.4
Since CP > SP we have loss
Loss % = ((CP) - (SP) / CP × 100)%
Loss % = (2 - 0.4)/2 * 100 = 80%
Loss % = 80%
