Question
'A' sold an article whose cost price is Rs. 'Z', at a
profit of 30% to 'B'. 'B' marked the price of the article 30% above the price at which he bought it from 'A' and sold it for Rs. 9,360 after giving a discount of 10%. Find the value of (Z - 6,000).Solution
ATQ, Cost price of the article for 'B' = 130% of Z = Rs. '1.3Z' So, marked price of the article = 130% of 1.3Z = (1.3) X (1.3Z) = Rs. '1.69Z' And selling price of the article = (0.9) X (1.69Z) = Rs. '1.521Z' So, 1.521Z = 9,360 Or, Z = (9360/1.521) = 6,150 So, required value = 6,150 - 6,000 = 150
