Question
Rahul sold a computer after giving a discount of 10% and
earned a profit of Rs. 1200. If he had sold it for Rs. 300 less, he would have earned a profit of 15%. Find the cost price of the computer.Solution
ATQ, Let the marked price be Rs. 100x. Selling price after 10% discount = 90x Cost price C=90x−1200 From the condition: 1.15×C=90x−300 Substituting C=90x−1200, 1.15×(90x−1200)=90x−300 103.5x−1380=90x−300 13.5x=1080 x=80 So, the cost price C=90×80−1200=Rs.6000
