    A. Answer:  (2) 84

    Explanation:-
    4 x 3 x 2 + 8 = 32,
    5 x 3 x 1 + 9 = 24,
    7 x 3 x 3 + 7 = 70,

    Similarly,
    2 x 9 x 4 + 12 = 84

    Hence, the answer is (2) 84.

    B. Answer : (2) 729

    Explanation:-
    The cube of 7 = 7 x 7 x 7 = 343,
    The cube of 8 = 8 x 8 x 8 = 512,
    The cube of 9 = 9 x 9 x 9 = 729.

    Hence, the answer is (2) 729.

    The square of prime number and add 1.
    Then,
    square of 2 = 2 x 2 + 1 = 5,
    square of 3 = 3 x 3 + 1 = 10,
    square of 5 = 5 x 5 + 1 = 26,
    square of 11 = 11 x 11 + 1 = 122.

    Hence, the answer is (3) 26.

    D. Answer: (1) 84

    Explanation:-
    11 x 12 – 6 x 9  = 132 – 54 = 78.

    14 x 10 – 7 x 8 = 140 – 56
    = 84

    Hence, the answer is (1) 84.
