      C Both Statements I and II together. Correct Answer Incorrect Answer
      D Neither Statement I nor II is sufficient. Correct Answer Incorrect Answer
      E Either Statement I or II. Correct Answer Incorrect Answer

      Solution

      From Statement I: Let the CP and MP of be Rs “13x” and “15x” respectively. SP = 15x × 90/100 = 13.5x (13.5x – 13x) = 45 0.5x = 45 x = 90 Therefore, MP = Rs. 15x = 15 × 90 = Rs. 1350 From statement I alone we can find the mark price. Now, From Statement II: MP – CP = 30------(i) SP – MP = 16-------(ii) MP = 30% of CP MP = 3/10 CP Putting the value of MP in equation i), we get 3/10CP – CP = 30 -7CP = 30 CP = -30/7, Value cannot be in -ve. So, we cannot find the MP from statement II.
