Question

The cost price of 25 articles is equal to the selling price of 20
articles. Find the gain %:
-(a) 25%
(b) 35%
(c) 30%
(d) 40%​

Answer 1

Answer:a)25%

Step-by-step explanation:

Let the C.P of 1 article be 100

C.p. 25 Article = 25×100=2500

S.P of 20 article= C.P of 25 Article

S.P of 20 = 2500

S.P of 1 Article= 2500/20=125

Since C.p. is smaller than S.p there is a profit,

Profit%= profit/c.p.× 100

=(125-100)/100×100

=25/100×100

=25%

thus gain of 25%
