Adam works at a constant rate and stuffs 400 envelopes in 2 hours. How much less time would it take to stuff the same number of envelopes if Adam and Matt worked together?
(1) Adam and Matt stuff envelopes at the same rate.
(2) It takes Adam twice as long to stuff all of the envelopes as it takes Adam and Matt to stuff all of them together.

If the question was the percentage less it would be D, but as the question ask for a number less it’s E.
In the two statements it’s clear that together is half of the time as Adam alone, but we don’t have a number to say how much less.

I'm sorry I don't understand. We are given that Adam stuffs envelopes at 200/hour and we want to know how less time it would take the work.
1 - Adam and Matt do work at same rate so together it would take them 1 hour to stuff 400 envelopes so it would be 1 hour less. [Sufficient]
2 - It takes Adam twice as long to do the work as it would take them together and we already know that it takes Adam 2 hours so it would take them 1 hour. [Sufficient]
Since the data is independently sufficient, doesn't it make it D?
