1 Answer(s)
  1. 42

    Explanation:-
    6 + 6 = 12,  12 + 6 + 2
     = 12 + 8 
     = 20,
    20 + 8 + 2 
     = 20 + 10 
     = 30,
    30 + 10 + 2
     30 + 12
     = 42

    Then, the missing number is 42. 

    Hence, the correct answer is option (d) 42. 

  2. 70 

    Explanation:-
    26 + 11 = 37, 
    37 + 11 = 48, 
    48 + 11 = 59, 

    Same as, 
    59 + 11 = 70.

    Then, the missing number is 70. 

    Hence, the correct answer is (a) 70. 

  3. 17/21

    Explanation:-
    (2 + 5)/(3 + 6) = 7/9,
    (7 + 5)/(9 + 6) = 12/15,

    Same as, 
    (12 + 5)/(15 + 6) = 17/21

    Then, the next number is 17/21.

    Hence, the correct answer is option (b) 17/21.

  4. 19

    Explanation:-
    15 + 20 = 35  &  10  + 2 = 12, 
    35 + 20 + 5 = 60  &  12 + 3 = 15,
    60 + 30 + 5 =  90  &  15 + 4 = 19. 

    Then, the next number is 19. 

    Hence, the correct answer is (d) 19. 

  5. 64 

    Explanation:-
    2^2 = 2 x 2
     = 4, 
    4^2 = 4 x 4
     = 16, 
    6^2 = 6 x 6
     = 36

    Same as, 8^2 = 8 x 8
     = 64.

    Hence, the correct answer is option (c) 64.
