Question

The cost price of 25 articles is the same as the selling price of 35 articles. Find gain or loss %.​

Answer 1

Answer:

Selling price = 35

cost price = 25

profit = sp-cp

profit 35-25

profit 10

gain percent = profit × 100 / cp

gain percent = 10× 100/ 25 = 28.5714%

Answer 2

Given :-

• The cost price ( CP ) of 25 articles is equal to the selling price ( SP ) of 35 articles

To Find :-

• What is the percentage of gain or loss ?

Solution :-

~Here,

→ Let the cost price of 1 article be Rs. 1

Then,

→ Cost price of 25 eggs will be Rs. 25

According to the Question ,

→ CP of  25 eggs = SP of 35 eggs

→ SP of 35 eggs = Rs. 25

→ SP of 1 egg = Rs. 25/35

_____________

~Here, we can see that cost price is more than selling price which means it is loss. Now, we can easily find the loss percentage by putting the values in it's formula.

As we know that ,

★ Loss % = ( CP - SP ) / CP × 100

Finding the Loss% :-

⟶ Loss % = ( 1 - 5/7  )/1 × 100

⟶ Loss % = 2/7 × 10

⟶ Loss % = 2.85 %

_____________

Therefore ,

• Loss percentage is of 2.85 %
