1 Answer(s)
  1. (b) 8 

    Explanation:-
    Sum of the square of 2 and 3 =4 + 9
    = 13,
    Sum of square of 7 and 3 = 49 + 9
    = 58

    Sam as,
    (5)^2 + (?)^2 = 89
    25 + (?)^2 = 89
    (?)^2 = 89 – 25
    (?)^2 = 64
    Square root on both side,
    ? = 8

    Then the value of ? is 8.

    Hence, the correct answer is option (b) 8.

  2. (c) 10 

    Explanation:-
    2 x 4 = 8,     2 x 6 = 12,     3 x 12 = 36

    Same as,
    ? x 2 = 20
    ? = 20/2
    ? = 10

    Then, the value of ? is 10.

    Hence, the correct answer is option (c) 10.
