Question

John 100eggs
for rupees 40 out of this 4 eggs where found to be broken and he sold the remaining eggs at the rate of 7.50 per dozen find the gain or loss percent

Answer 1

John brought eggs in place of 100 rupees
He had payed 2.5 rupees for each one
But 4 eggs had broken
That means he had sold 96 eggs
If he had sold 1 dozen eggs in place of 7.50 rupees, he got .8rupees for each one
So, he had collected 76.8 rupees by selling all eggs
That means he lost 23.2 rupees or 23.2%

Answer 2

c.p=100÷40=2.5
s.p.=7.50÷12=0.625
loss = c.p - s.p
=2.5 - 0.625
=1.875
loss percent=loss÷ c.p ×100
=1.875÷ 2.5×100
=75 percent
