Tom takes 20 minutes to cook an egg and 5 minutes to make a sandwich, which means he spends 25 minutes in total for one egg and sandwich. On the other hand, Jerry takes 15 minutes to cook an egg and 3 minutes to make a sandwich, which means he spends 18 minutes in total for one egg and sandwich.

If they specialize and trade, Tom can focus on cooking eggs, which takes him 20 minutes, while Jerry focuses on making sandwiches, which takes him only 3 minutes. Once they finished, they exchange the items. Therefore, it would take them a total of 23 minutes for one egg and one sandwich in total.

This way, they both benefit as they can save a total of 2 minutes per set, compared to if they did everything themselves. So choice E, both of them benefit, is the best answer.
