Let the cost price of article βAβ = Rs. β100yβ Then, selling price of the article when it is sold at a profit of 55% = 1.55 Γ 100y = Rs. β155yβ And, selling price of the article when it is sold at a loss of 45% = 0.55 Γ 100y = Rs. β55yβ According to the question, 155y β 55y = 200 Or, y = (200/100) Or, y = 2 So, cost price of article βAβ = 100 Γ 2 = Rs. 200 Therefore, cost price of article βBβ = 200 + 80 = Rs. 280
