Hi
egmatCan we use your LCM method in this type of problem ? I wasnt able to solve through LCM and ended up choosing 2/5.
Hi,
Could you please show us, how you approached at solving this question, so that we can understand it in a better way

Hi,
I am sorry, I discarded the worksheet, before I saw your reply. But I tried solving this again and I ended up with correct answer although it logically doesnt make sense to me, if you could review that would be great:
So, A : B, 5x : 6x
As the employees for A are three times more efficient, that means one employee of "A" can work as much as three employees of "B".
So 5 * 3 = 15, so the ratio 15x : 6x; so now taking the LCM of 15 and 6 we get 30, from here on my answer doesn't logically make sense to me.
for A 30/15 = 2
for B 30/6 = 5
so total work is "7" and therefore 2/7. after solving I realized the question is asking for the part of work done by "B".
