Question

A grocer buys eggs at 10 for rupees 8 and sell at 8 for rupees 12 find his gain or loss by selling 40 eggs.
please answer guys.....

Answer 1

Answer:

Cost price per egg = 8/10 = 0.8.

Selling price per egg = 10/8 = 1.25.

Gain = 1.25 - 0.8 = 0.45

%gain = (0.45 *100)/0.8 = 56.25%.

I Hope it will help!

Answer 2

Hey There!

___________________________

According to Question, Buys eggs means, C.P of 10 eggs = ₹8

And S.P of 8 eggs = ₹12

Therefore, C.P of 1 egg = ₹$\frac{8}{10}$ = ₹0.8

S.P of 1 egg = ₹$\frac{12}{8}$ = ₹1.5

Gain = S.P - C.P

Gain = ₹1.5-0.8

Gain = ₹0.7 on each egg .

Gain for 40 Eggs = $40\times \frac{7}{10}$

$4{\cancel{0}} \times \frac{7}1{\cancel{0}}$

Therefore, Gain = ₹28

$Gain \% = \frac{Gain\times100}{C.P}$

Therefore, $Gain \% = \frac{0.7\times100}{\frac{8}{10}}$

Therefore, $Gain \% = \frac{0.7\times100\times10}{8}$

$Gain\% = \frac{7\times100}{8}$

$Gain\% = \frac{700}{8}$

$Gain\% = 87.5$
