% profit/loss = {(m-n)/ n } *100 = {(20-25)/ 25 } *100 = -5/25 * 100 =-20%

-ve sign implies it is a loss of 20%

step-by-step explanation:

let,

Cost price of 25 pens = ₹ 1

then,

Cost price of 1 pen = ₹ 1/25

Now,

let,

Selling price of 1 pen = ₹ x

then,

selling price of 20 pen = ₹ 20x

given,

CP of 25 pens = SP of 20 pens

=> 20x = 1

=> x = 1/20

so,

SP of 1 pen = ₹ 1/20

.°. Gain = SP - CP

= ₹ (1/20 - 1/25) { considering 1 pen }

= ₹ 1/100

therefore,

gain % = (gain / C.P × 100)%

= {(1/100)/(1/25) × 100}%

= (2500/100)%

= 25%

hence,

profit % = 25%
