Question

a grocer buys eggs at 10 for rupees 8 and sells at 8 for rupees 10. find his gain or loss per cent​

Answer 1

Answer:

C.P of 10 eggs = rs 8

Therefore, CP of 1 egg = 8/10 = 4/5

S.P of 8 eggs = rs 10

And, S.P of 1 egg = 10/8 = 5/4

Therefore, profit = S.P - C.P

=5/4 - 4/5

=(25 - 16)/20

=9/20

So,profit % = (9/20)÷4/5 x 100

=(9/20) x (5/4) x 100

=225/4 %

=56.25 %

Answer 2

Step-by-step explanation:

Given:

C.P. of 10 eggs = 8 rupees

S.P. of 8 eggs = 10 rupees

So,

C.P. of 1 egg = 8/10 = 4/5 rupees

similarly, S.p. of 1 egg = 10/8 = 5/4 rupees

It is a gain.

gain= s.p. - c.p.

= 5/4 - 4/5

= 9/20 rupees

gain% = 9/20 ÷ 4/5 ×100

= 56.25 %
