It takes the average dryer 80 minutes to dry one full load of Bob's laundry. Bob has
one average dryer, and also decides to try one "Super Jumbo-Iron Dryer-Matic",
which is faster than the average dryer by a ratio of 5 : 4. Bob has three loads of
laundry, and both machines are so precise that he can set them to the minute. How
many minutes does it take for him to dry his three loads? (Assume that no time
passes between loads and that he can use both machines concurrently. Assume also
that he never runs a machine with less than a full load. Finally, assume that Bob
is allowed to partially dry a load in one machine and then switch it to the other.)
This is from MGMAT Word Translations Guide. The problem is solved for Bob not allowed to partially dry a load.
My question is, if Bob partially dries a load then how can it be solved. I am not able to understand the MGMAT soln.
Plz help.
Ans: 107 mins (approx)

"Your time is limited, so don't waste it living someone else's life. Don't be trapped by dogma - which is living with the results of other people's thinking. Don't let the noise of others' opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary" - Steve Jobs
