At a loading dock, each worker on the night crew loaded 3/4 as many boxes as each worker on the day crew. If the night crew has 4/5 as many workers as the day crew, what fraction of all the boxes loaded by the two crews did the day crew load?

A. 1/2 B. 2/5 C. 3/5 D. 4/5 E. 5/8

My strategy of answering this question was not efficient. I am curious to know if you all approach the same as OG. OA to follow.

Haven't checked OG but my method is below and i suppose it would be the standard way.

Ans is E.

Method: X = No. of boxes loaded by day crew.
Boxes by night crew = 3/4 * 4/5 X = 3/5 X

When I see problems such as these I generally pick #'s. I guess my problem was that I picked bad #'s and that is the key to the method working. Must note that in error log Anyway, OG solved as Saha (and most of you) did. OA is E. Thanks

E Pick numbers.
Let there be 5 day workers and so, 4 night workers
Let each day worker load 4 boxes and so, each night worker loads 3 boxes
Total boxes loaded = 5*4 + 4*3 = 32.
