Question

the cost price of 30 article is same as the selling price of x article if the profit is 20% find the value of x

Answer 1

Answer:

Let C.P of each article be Re. 1.

C.P of x articles = Rs. x and S.P of x articles = Rs. 20.

Profit = Rs. (20 - x).

∴20−x/x ×100 =25

⟹2000 - 100x = 25x

⟹ 125x = 2000

⟹ x = 16.
