Question

The CP of 25 articles is equal to the SP of 30 articles . Find the profit and loss percentage .​

Answer 1

Answer:

16.67%

Step-by-step explanation:

CP of one article = a\25

SP of one article= a\30

loss= a/25 - a/30

= 6a - 5a

__________

150

loss= a/150

loss%=a /150×100

___________

a/25

= 250/15

= 50/3

[=16.67%]

Answer 2

Answer:

Loss = 16.67%

Step-by-step explanation:

Assume cost price(CP) of 1 article = x

Therefore cost price of 25 articles = 25x

Given cost price of 25 article = selling price of 30 articles

Clearly, it is a loss.

Selling price(SP) of 30 articles = 25x

$So , \ selling \ price\ of\ one\ article = \frac{25x}{30}\\\\Therefore , Loss \% = \frac{CP - SP}{CP} \times 100$

                            $=\frac{x - \frac{25x}{30}}{x } \times 100\\\\=\frac{30x - 25x }{30x }\times 100\\\\=\frac{5}{30} \times 100\\\\=16.67 \%$
