Question 12 topscore test 2. Basically its a simle rate problem
A can do 5000 piece order in 4 days and B in 5 days how long will it take if both work together (they add a lot of wording to make it sound hard but its as simple as this)
4/20 +5/20=9/20 =1/T so Time=20/9 or 2 and 2/9 days
or 4*5/4+5 also = 20/9
There was no choice that said 2 and a fraction days but there was 3 1/2 and also 4 1/2 they say to pick 3 because you need 3 days but it seems ridiculous to me. If you are going to round that generously then all the answer choices should be whole numbers, not some whole, some fractions and the answer choice (as a fraction not given) being quite far off from the real answer. I wasted 2 mins on this question because i knew it was so easy and I was probably making an easy mistake and KNEW i could get it. I understand 3 is the best choice but it threw me off seeing other fractions but not the one I wanted. Wow really needed to vent!
