Question
Selling price of article βAβ when sold at a profit
of 50% is Rs. 180 more than its selling price when sold at a loss of 40%. If the cost price of article βBβ is Rs. 80 more than that of βAβ, then find the cost price of article βBβ.Solution
Let the cost price of article βAβ = Rs. β100yβ Then, selling price of the article when it is sold at a profit of 50% = 1.50 Γ 100y = Rs. β150yβ And, selling price of the article when it is sold at a loss of 40% = 0.60 Γ 100y = Rs. β60yβ According to the question, 150y β 60y = 180 Or, y = (180/90) Or, y = 2 So, cost price of article βAβ = 100 Γ 2 = Rs. 200 Therefore, cost price of article βBβ = 200 + 80 = Rs. 280
