Question

the selling price of 20 articles is equal to the cost price of 22 articles find the gain percent​

Answer 1

Here, a = 22 and b = 20, then

Therefore, Gain% = a−bb×100%

= 22−2020×100% = 10%

Answer 2

Answer:

Profit % is 10%

Step-by-step explanation:

S.P of 20 articles = C.P of 22 articles .

Let the C.P of one article be x.

C.P of 22 articles = 20x ( S.P of 20 articles same)

S.P of 20 articles=22x

If S.P>C.P= Profit.

Profit=S.P-C.P

=22x - 20x

=2x

Profit %=Profit/C.P x 100%

=2x/20x * 100%

=100/10

=10%
