  • Question
  • 24   7     81
    x     27    19
    If 'x' is the resultant of the first row, what will be the resultant of the second row?


  • Options
  • A. 87
  • B. 114
  • C. 4
  • D. 6

  • Correct Answer


  • Explanation

    Rules
    (i) (2-digit even number) ÷ ( Even number)
    (ii) (Even number) x (Prime number)
    (iii) (Odd number) + (Odd number)
    (iv) (3-digit number) - (2-digit perfect square number)
    (v) (3-digit number) ÷ (2-digit non-perfect square number)
    Solution
    1st Row 24   7   81 ? 24 x 7 = 168       [rule (ii)]
    ?     168 - 81 = 87     [rule (iv)]
            = x
    2nd Row x   27   19 ? 87   27   19
    ?         87 + 27 = 114     [rule (iii)]
    ?         114 ÷ 19 = 6     [rule (v)]
    ? Resultant of second row = 6
