    1. Answer: (d) 45

      Explanation:-

      4 x 2 = 8,             8 x 2 = 16,       16 x 2 = 32.
      5 x 3 = 15,        15 x 3 = 45,       45 x 3 = 135.
      6 x 4 = 24,         24 x 4 = 96,        96 x 4 = 384.

      Hence, the answer is (d) 45. 

    2.  Answer: (c) 4

      Explanation:-

    3.  Answer:  (b) 75

      Explanation:-
      8 x 4 + 9 x 5 = 32 + 45
       = 77,

      Same as, 
      7 x 3 + 9 x 6 = 21 + 54
       = 75,

      Hence, the answer is (b) 75.

    4.  Answer:  (a) 5 

      Explanation:-
      8 + 7 = 15,
      The square of 15 = 15 x 15 
       = 225,

      4 + 3 = 7,
      The square of 7 = 7 x 7 
       = 49,

      Same as,
      6 + 5 = 11,
      The square of 11 = 11 x 11
       = 121.

      Hence, the answer is (a) 5.
