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.
Gentle note to all experts and tutors: Please refrain from replying to this question until the Official Answer (OA) is revealed. Let students attempt to solve it first. You are all welcome to contribute posts after the OA is posted. Thank you all for your cooperation!

Rate of J = 300/4 = 75
S1
Time taken J is 2 times the time taken by J&P
So, J&P will take only 2hrs to produce 300 bottles together
So, they will take 2hrs less
Sufficient
S2
Machines J and P both started at 6 a.m.
This tells nothing about the rate of P&J
Insufficient
