Question

salim bought 180 eggs for Rs 400. out of these 30 eggs were found to be broken. he sold the remaining eggs at Rs 28 per dozen. find his profit or loss lercent.​

Answer 1

$Egg= 180- 30=150$

$Cp \: of \: 150 \: Egg = Rs \: 400$

$Cp \: of \: 1 \: Egg = Rs \frac{400}{150} = 2.66$

$Sp \: of \: 12 \: egg = 2.66$

$Sp \: of \: 2 egg = \frac{28}{12} = 2.33$

$Profit \: \% = \frac{Sp - Cp}{ Cp?} \times 100$

$Profit \: \% = \frac{2.33 - 2.66}{2.66} \times 100$

$Profit \: \% = \frac{0.33}{2.66} \times 100$

$Profit \: \% = - 0.12 \times 100$

$Profit \: \% = - 12$
