    To solve this problem, let us assign the variables. Let us say that:

    x = age of Tony = which also the age of his twin brother Evan

    x + 4 = age of Josh (since tony is 4 years younger, then josh must be 4 years older)

    x - 2 = age of Cindy (since tony is 2 years older, then cindy must be 2 years younger)

    There are a total of 4 children, therefore:

    x + x + x + 4 + x - 2 = 66

    4 x + 2 = 66

    4 x = 64

    x = 16

    Therefore Tony is 16 years old.
