tom is 57 years old. Tom has a son, james. In 3 years tom will be twice as old as james. How old is james

27 years

Step-by-step explanation:

In three years, Tom will be 57 + 3 = 60 years old.

Since Tom will be twice as old as James at that time, then James will be half his age, or 60/2 = 30 years old.

If James is going to be 30 years old in three years, then he is 27 years old now.

Answer: 27

Step-by-step explanation:

Tom is 57 now. In 3 years he will be 60, but also twice as old as his son. 1/2 of 60 is 30. 30 minus the 3 years that hasn't happened yet equals 27.
