ARTICLES are in the ratio of 3 : 2 respectivelyFormula USED: Selling price = Cost price + profitSelling price = Cost price – lossCalculation: Let the cost price of two articles be 3Y and 2y respectively, thenWhen the price of first article is increased by 40%Price of first article = 3y + (40/100) × 3y = 4.2y When the price of second article is increased by x%Price of first article = 2y – (x/100) × 2y = 2y – 2xy/100Now,⇒ (4.2y)/(2y – 2xy/100) = 7 ∶ 3⇒ 12.6y = 14y – 14xy/100⇒ 14xy/100 = 1.4y⇒ x = 10%∴ VALUE of x is 10
