Explanation

Let CP1 = 3x, CP2 = 4x. SP1 = 3x * 1.2 = 3.6x. SP2 = 4x * 1.4 = 5.6x. Ratio SP1:SP2 = 3.6:5.6 = 36:56 = 9:14.

AI explanation

Let the cost prices be 3 and 4 according to the given ratio. The selling price of the first article is 3 multiplied by 1.20, which is 3.6. The selling price of the second article is 4 multiplied by 1.40, which is 5.6. Finding the ratio of the selling prices gives 3.6 to 5.6, which simplifies to 9 to 14.
