  • Question
  • 125   64   33
    282    x     39
    If 'x' is the resultant of the first row, what will be the resultant of the second row?


  • Options
  • A. 45
  • B. 42
  • C. 39
  • D. 36

  • Correct Answer
  • 42 

    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 125   64   33 ? 125 - 64 = 61       [rule (iv)]
    ?     61 + 33 = 94     [rule (iii)]
            = x
    2nd Row 282   x   39 ? 282   94   39
    ?         282 ÷ 94 = 3     [rule (v)]
    ?         3 + 39 = 42     [rule (iii)]
    ? Resultant of second row = 42
