Answer 1

Answer:

he has a gain

Step-by-step explanation:

Answer 2

Answer:

His gain% is 50%.

Given:

A shopkeeper buys a dozen eggs at Rs.60.

He sells them at 10 for Rs.75.

To find:

His gain or loss percent.

Solution:

C.P of 12 eggs = Rs.60

C.P of 1 eggs = Rs. 60/12 = Rs.5

C.P of 10 eggs = Rs.10×5 = Rs.50.

S.P of 10 eggs = Rs.75

Gain = S.P-C.P

Gain = Rs.75-Rs.50 = Rs.25.

$gain\% \: = \frac{gain}{cp} \times 100$

$= > \frac{25}{50} \times 100$

$= > 50.$

Hence, gain% on eggs is 50%.

Something more related to it:

$profit \: = sp - cp$

$loss \: = cp - sp$

$profit\% \: = \frac{profit\%}{cp} \times 100$

$loss\% \: = \frac{loss}{cp} \times 100$

$sp(when \: profit\% \: is \: given) \\ = > ( \frac{100 + profit\%}{100}) \times cp$

$sp(when \: loss\% \: is \: given) \\ = > ( \frac{100 - loss\%}{100}) \times cp$

$cp(when \: profit\% \: is \: given) \\ = > ( \frac{100}{100 + profit\%}) \times sp$

$cp(when \: loss\% \: is \: given) \\ = > ( \frac{100}{100 - loss\%}) \times sp$
