      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.

      B Rs.6500 Correct Answer Incorrect Answer
      C Rs.6000 Correct Answer Incorrect Answer
      D Rs.4000 Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      ATQ, Let the marked price be Rs. 100x. Selling price after 10% discount = 90x Cost price C=90xโˆ’1200 From the condition: 1.15ร—C=90xโˆ’300 Substituting C=90xโˆ’1200, 1.15ร—(90xโˆ’1200)=90xโˆ’300 103.5xโˆ’1380=90xโˆ’300 13.5x=1080 x=80 So, the cost price C=90ร—80โˆ’1200=Rs.6000
