  • Question
  • 15   8   21
    p     3    27
    If 'p' is the resultant of the first row, what will be the resultant of the second row?


  • Options
  • A. 58
  • B. 76
  • C. 27
  • D. 82

  • Correct Answer
  • 58 

    Explanation

    Rules
    (i) (odd number) + (Composite odd number)
    (ii) (Even number) + (Odd number)
    (iii) (Even number) ? (Perfect square number), then (Perfect square number) - (Even number)
    (iv) (Odd number) ÷ (Prime odd number)
    (v) (Odd number) - (Even number)
    1st Row   15   8   21 ? 15 - 8 = 7     [rule (v)]
    ?       7 + 21 = 28     [rule (i)]
    2nd Row   p   3   27 ? 28   3   27
    ? 28 + 3 = 31     [rule (ii)]
    ? 31 + 27 = 58     [rule (i)]
    ? Resultant of second row = 58
