Answer 1

$\huge\star\underline\mathfrak\red{Answer:-}$

1)

Cp of 20 eggs = 56

Cp of 1 egg = 56/20 = 2.8

SP of 12 eggs = 35

Sp of 1 egg = 35/12 = 2.92

Profit = SP - cp

= 2.92 - 2.8 = 0.12

Profit% = profit *100/cp

= 0.12 * 100 / 2.8

= 4.28%

2) her c.p=7,700

her total or net c.p=7,700 + 1,000=8,700

profit = 5%

now,

s.p = c.p + 5%of c.p

s.p = 8,700 +5% of 8,700

    = 9135
