Question
An object is sold at a 15% gain and the selling price
becomes Rs. 180 more than when it's sold at a 35% loss. Find the cost price of the object.Solution
ATQ,
Let the cost price of the object = Rs. 100x
According to the question,
(100x Γ 1.15) β (100x Γ 0.65) = 180
β 115x β 65x = 180
β 50x = 180
β x = 180 Γ· 50 = 3.6
β΄ Cost price = 100x = 3.6 Γ 100 = Rs. 360
