Question

salma sells 18 eggs at the price for which she buys 20 eggs find profit or loss percentage

Answer 1

Solutions :-

Given :
Salma sells 18 eggs at the price for which she buys 20 eggs.


Find the LCM of 18 and 20 :-

LCM of 18 and 20 = 180


Therefore,
Selling price of 18 eggs = Rs 180
Selling price of 1 egg = 180/18 = Rs 10

Cost Price of 20 eggs = Rs 180
Cost Price of 1 egg = 180/20 = Rs 9


Selling price is greater than the Cost price. Therefore, Profit.

Profit = S.P - C.P
= Rs (10 - 9) = Rs 1


Profit% = (profit × 100)/C.P %
= (1 × 100)/9 %
= 100/9 %
= 11.11 %


Hence,
Profit percentage = 11.11 %

Answer 2

Solutions :-

We have,
Salma sells 18 eggs at the price for which she buys 20 eggs.

Here, given
Selling price = Rs 20
Cost Price = Rs 18

Selling Price > Cost price

Profit = SP - CP
= Rs (20 - 18)
= Rs 2

Profit percent = (profit × 100)/C.P %
= (2 × 100)/18 %
= 200/18 %
= 11.11 % approx.


Answer : Profit percentage = 11.11 %
