    Question

    Study the given pattem carefully and select the number from among the given options that can replace the question mark (?).
    24 $ 34 = 68
    31 $ 26 = 67
    17 $ 52 = ?

    A.

    58

    B.

    79

    C.

    15

    D.

    16

    Correct option is B

    Given:
    ​24 $ 34 = 68
    ​31 $ 26 = 67
    ​17 $ 52 = ?

    Logic:  $ Sign is + and add +10 to get the number. 
    Lets analyze the pattern by replacing $ with +.
    Pattern 1:
    24 + 34 = 58
    58 + 10 = 68
    Pattern 2:
    31 + 26 = 57
    57 + 10 = 67
    Pattern 3:
    Follow the previous patterns.
    17 + 52 = 69
    69 + 10 = 79
    Thus, the correct option is B.
