Machine J runs at a constant rate and produces a lot consisting of 300 bottles in 4 hours. How much less time would it take to produce the lot of cans if both machines J and P were run simultaneously?

(1) It takes machine J twice as long to produce the lot of cans as it takes machines J and P running simultaneously to produce the lot.
(2) Machines J and P both started at 6 a.m.

Looks like A is the answer.

1. J takes twice the time J and P would take i.e. 2 hrs extra. Sufficient.
2. Info that they start at 6 am Doesn't add any value to the question. Insufficient.

IMO :A

STMT 1 -- J takes "twice" as long to produce the lot of cans as it takes machines J and P running simultaneously to produce the lot. 2 hours less time
STMT 2: what time they started is irrelevant to our question.
