Question
Item βXβ had a cost price of Rs. 800 and it was
marked up by 25%. It was later sold after giving a discount of Rs. 40. Another item βYβ was sold for Rs. 900 at a loss of 10%. What is the ratio of the cost price of item βYβ to the selling price of item βXβ?Solution
ATQ,
Marked price of item βXβ = 800 Γ 1.25 = Rs. 1,000 Selling price of item βXβ = 1,000 β 40 = Rs. 960 Cost price of item βYβ = 900 / 0.90 = Rs. 1,000 So, required ratio = 1000:960 = 25:24
