Digimon had its 20th anniversary. When it came out John was twice as old as Jim. If John is 28 now how old is Jim?

How old was John when Digimon came out? ** When Digimon came out John would have been 28-20=<<28-20=8>>8
How old was Jim when Digimon came out? ** So Jim was 8/2=<<8/2=4>>4 years old
How old is John now? ** That means John is now 4+20=<<4+20=24>>24
