Tom's brother is 4 times as old as Tom's dog. If in 6 years, Tom's brother will be 30 years, how old is Tom's dog going to be in six years?
Tom's brother is [NUMBER] times as old as Tom's dog. If in [NUMBER] years, Tom's brother will be [NUMBER] years, how old is Tom's dog going to be in [NUMBER] years?
If in six years Tom's brother will be 30 years old, he is currently 30-6 = <<30-6=24>>24 years old.
Since Tom's brother is 4 times as old as Tom's dog, Tom's dog is 24/4 = <<24/4=6>>6 years old currently.
Tom's dog will be 6+6 = <<6+6=12>>12 years old in six years.
