Selling price of article βAβ when sold at a profit
of 50% is Rs. 100 more than its selling price when sold at a loss of 30%. 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 30% = 0.70 Γ 100y = Rs. β70yβ According to the question, 150y β 70y = 100 Or, y = (100/80) Or, y = 1.25 So, cost price of article βAβ = 100 Γ 1.25 = Rs. 125 Therefore, cost price of article βBβ = 125 + 80 = Rs. 205
