    1. Answer: (d) 24

      Explanation:-
      -1 + 1 = 0,  0 + 1 + 2
       = 0 + 3 = 3, 
      3 + 3 + 2 = 3 + 5
       = 8, 
      8 + 5 + 2 = 8 + 7
       = 15,
      Similarly, 15 + 7 + 2 
       = 15 + 9 
       = 24

      Then, the missing number is 24. 

      Hence, the correct answer is option (d) 24. 

    2. Answer: (c) 6, 15

      Explanation:-
      6 + 3 = 9  &  2 + 2 = 4, 
      4 + 2 = 6  &  9 = 3 = 12.

      Then, the missing numbers are 6, 15. 

      Hence, the correct answer option (c) 6, 15. 

    3. Answer: (a) M

      Explanation:-
      The opposite place values of A C E = Z X V, 
      And E + 2 = G, 
      The opposite place values of G I K = T R P, 

      Same as, K + 2 =  M. 
      Then, the missing number is M. 

      Hence, the correct answer is option (a) M. 

    4. Answer: (a) Z 

      Explanation:-
      A + 3 = D,  D + 4 = H,  H + 5 = M,  M + 6 = S. 

      Same as,  S  + 7 =  Z. 

      Hence, the correct answer is option (a) Z.
