Question

17. The cost price of 30 eggs is equal to the sale price of 20 eggs. What is the
percentage of profit
​

Answer 1

Answer:

50 % profit

Step-by-step explanation:

30 cp = 20 sp

cp/sp=20/30

now, profit = sp-cp= 30-20= 10

profit percent = profit/ cp ×100

= 10/20 ×100 = 50 %

Answer 2

Step-by-step explanation:

Let the cost of 1 egg = rs 1

Cp of 30 eggs = s.p.of 20 eggs

S. P. Of 1 egg =30/20= rs 1.5

S. P. of 30 eggs =30*1.5=45

Profit = s. P.- c.p.

45-30=15

Profit%=profit/c.p.*100

=15/30*100=50%
