Answer 1

C. Q-A Shopkeeper buys eggs at Rs 15 a dozen and sells them at 7 for Rs 4 . Find his profit and loss % .

Solution:
________

since, we know 1 dozen eggs = 12 eggs

c.p of 12 eggs = Rs 15

c.p of 1 egg = 15/ 12 = 5/ 4

s.p of 7 eggs = Rs 4

s. p of 1 egg = Rs 4/ 7

loss = 5/ 4 - ( 4/ 7) = Rs 19/ 28

loss % = (loss × 100)/ c.p

(19/28 × 100)/ 5/ 4

=( 1900 × 4)/ 28 × 5 = 54.28 %

Answer: his overall loss% = 54.28%
