Tony is four years younger than his brother josh, and two years older than his sister cindy. tony also has a twin brother, evan. all the ages of the children totaled together is 66. how old is tony?

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.
