Question
Cost price of an item is Rs. (12n + 240). It is marked 50%
above its cost price and sold after allowing a discount of Rs. (2n + 40). If the profit earned is Rs. 1,360, then find the value of 'n'.Solution
ATQ,
Marked price of item = 1.5 × (12n + 240) = Rs. (18n + 360)
Selling price of item = (18n + 360) - (2n + 40) = Rs. (16n + 320)
Profit earned = (16n + 320) - (12n + 240) = Rs. (4n + 80)
So, 4n + 80 = 1,360
Or, 4n = 1,280
Or, 'n' = 320
