Question
'A' sold an article whose cost price is Rs. 'V', at a
profit of 10% to 'B'. 'B' marked the price of the article 10% above the price at which he bought it from 'A' and sold it for Rs. 4,950 after giving a discount of 10%. Find the value of (V - 3,500).Solution
ATQ, Cost price of the article for 'B' = 110% of V = Rs. '1.1V' So, marked price of the article = 110% of 1.1V = (1.1) X (1.1V) = Rs. '1.21V' And selling price of the article = (0.9) X (1.21V) = Rs. '1.089V' So, 1.089V = 4,950 Or, V = (4950/1.089) = 4,545 So, required value = 4,545 - 3,500 = 1,045
