  • Question 2/10
    1 / -0.25

    If ‘A’ is replaced by ‘+’; if ‘B’ is replaced by ‘– ‘; ‘C’ is replaced by ‘÷’ and ‘D’ replaced by ‘×’, find the value of the following equation.

    27 C 9 A 15 D 3 B 16

    Solutions

    After the replacements, the equation becomes:

    27 C 9 A 15 D 3 B 16 = 27 ÷ 9 + 15 × 3 – 16

    → 3 + 45 – 16 = 32

    Solutions

    Logic:

    117 – 10 = 107

    107 – 15 = 92

    92 – 20 = 72

    So, next term will be in succession

    72 – 25 = 47
