Question

35. If the ratio of cost price and sell-
ing price of an article is 4 : 5,

(1) 20
(3) 10
(2) 0.1
(4) 25​

Answer 1

let,

Cost price = 4x

selling price = 5x

profit % = (selling price - cost price)/ celling price × 100

= (5x - 4x) / 4x × 100

= (x ×100) / 4x

= 25

so the answer will be 25
