Quote:
A can manufacturing company has 5 identical machines, each of which produces cans at the same constant rate. How many cans will all 5 machines produce running simultaneously for z hours ?
Step 1: Understanding the questionLet rate of each machine be x, rate of 5 machines = 5x
Using Rate * Time = Work
5x * z = w
w = 5xz
w is to be calculated
Step 2: Understanding statement 2 alone(1) Running simultaneously, 3 of the machines produce 72,000 cans in 2z hours
3x * 2z = 72000
xz = 12000
Hence, w = 5*12000 = 60000
Sufficient
Step 3: Understanding statement 2 alone(2) Running simultaneously, 2 of the machines produce 24,000 cans in
z hours
2x * z = 24000
xz = 12000
Hence, w = 5*12000 = 60000
Sufficient
