Allen is 20 years older than his cousin jim. in 3 years, allen will be twice as old as jim. how old are allan and jim now

First of all this question makes no complate sense if this was in real life. But the answer is: Allen is 23 years old and Jim woukd be 12 1/2 years old.

Step-by-step explanation:

Because 20+3=23. That's because it said in 3 years. Tthen we divide by 2 to find Jim's age. That's because it said that in three years, Allen would be twice as old as Jim.
