  • Question
  • P, Q, R, S, T and U are six consecutive odd numbers and their average is 52. What is the product of P and U ?


  • Options
  • A. 2212
  • B. 2154
  • C. 2349
  • D. 2679

  • Correct Answer
  • 2679 

    Explanation

    Let x, x+2, x+4, x+6, x+8 and x+10 are six consecutive odd numbers.

    Given that their average is 52

    Then, x + x+2 + x+4 + x+6 + x+8 + x+10 = 52×6

    6x + 30 = 312

    x = 47

    So Product = 47 × 57 = 2679
