Best answer
Correct Answer - Option 2 : 16

Given:

20 CP = x SP

profit = 25 %

CP = cost price of article

SP = selling price of the article

Formula used:

Profit % = (Profit/CP) × 100

Here, SP → Selling price, CP → Cost price

Calculation:

20 CP = x SP

⇒ SP/CP = 20/x

Profit = (20 - x)/x

Given profit = 1/4

equating both

(20 - x)/x = 1/4

⇒ 80 = 5 x

⇒ x = 16
