_____________________________

[ 1 Dozen = 12 Units ]

We have,

Find the cost of 10 eggs =>

Cost of 10 dozen eggs = Rs 408
Cost of 1 dozen eggs = Rs 408/10 = Rs 40.8
Cost of 1 egg = Rs 40.8/12 = Rs 3.4
Cost of 10 eggs = Rs 3.4 × 10 = Rs 34

So, CP of 10 eggs = Rs 34

And SP of 10 eggs = Rs 50


SP > CP

So, Profit

Profit = SP - CP
= Rs ( 50 - 34 ) = Rs 16



Now,

$profit\% = \frac{profit}{cp} \times 100\% \\ = \: \frac{16}{34} \times 100\% \\ = 47.05\%$

Hence,

Profit % = 47.05%

Answer 2

Given :

10 dozen eggs = ₹ 408

______________________________

Finding eggs of ten dozen -

1 dozen = 12 eggs.

10 dozen = 10 x 12 = 120 eggs

______________________________

Finding CP of ten dozen eggs -

120 eggs = ₹ 408

10 eggs = ?

= 10 x 408 ÷ 120

= 34.

= CP is ₹ 34

______________________________

Finding profit -

CP of 10 eggs = ₹ 34

SP of 10 eggs = ₹ 50 ( given )

SP is more so profit .

Profit = SP - CP = 50 - 34 = 16

_______________________________

Finding profit percentage -

$profit \: percentage \: = \dfrac{profit}{cp} \times 100$

$= \: \dfrac{16}{34} \times 100 \: = 47.05\%$

$\bold{Answer: \: Profit \: percentage \: = 47.05 \%}$
