Question

A shopkeeper bought 200 pens and 300 pencils for a total of Rs.6000. he sold 40% pens at 20% profit and the rest pens at x% profit. he sold 60% pencils at 40% profit and the rest pencils at y% profit the shopkeeper got Rs.10400 by selling all the articles if he had got 35% profit on pencils then find x:y?​

Answer 1

Step-by-step explanation:

Assume that price of the pen is X

Initial Cost = 300 * X = 300X

As per given equation,number of pens sold at no profit/loss = 300 *( 1/4) = 75

Remaining pens sold at 20% profit = (300–75) * (X+X*(0.2)) = 270X

Total Profit = (75X + 270X) - 300X = 45X

Profit Percentage = (profit/Initial Cost) * 100 = (45X/300X ) * 100 = 15

So there is profit of 15% on whole transaction
