    Answer: (2) 68
    Explanation:-
    Let the number of pigeons is X and the number of rabbits is Y
    The total number of head = 90
    Then, X + Y = 90                            ………………………………..  (1)

    The  number of legs  = 224
    Then, 2 X + 4 Y = 224
    Both side divide by 2,
    X + 2 Y = 112                     ……………………………………………… (2)
    Solve equation (1) & (2)
    Y = 22   & X = 90 – 22 = 68
    Then, the number of pigeon in the zoo is 68.
    Hence, the answer is (2) 68.
