If Trevor's brother is 32 years old today then 20 years ago he was = 32-20 = <<32-20=12>>12 years old
If Trevor's brother was 12 years old and he was twice Trevor's age, then Trevor was 12/2 = <<12/2=6>>6 years old
If Trevor was 6 years old 20 years ago, then he must be 6 + 20 = <<6+20=26>>26 years old today
If Trevor is 26 years old today then a decade ago he must have been 26-10 = <<26-10=16>>16 years old
