  1. Answer:

    Your answer is (i) 12.

    (ii) 100.

    Step-by-step explanation:

    Let, the number be x.

    (i) According to the first point the equation will be,

    3x + 11 = 47

    3x = 47 – 11

    3x = 36

    x= 36 / 3

    x= 12.

    (ii)According to second point the equation will be,

    1/4x + 7 = 32

    1/4x = 32 – 7

    1/4x = 25

    x = 25×4 / 1

    x= 100.
