Running at their respective constant rates, machine A takes 2 days longer to produce W weights than machine B.Working together, they can finish 5W/4 in 3 days. How many days will it takes for A to finish 2W weights dependently?

Hi guys tried solving this one. I keep on getting 12 days but according to the official answer it is suppose to be 10 days.

I am also getting 12 days.
Let x = days taken by B to complete W weights

3W/(x+2) + 3W/x = 5W/4

solving this we get x = 4
So 2W work by A = (4+2)*2 = 12

Can you update the highlighted to 5W/4 and not 5/4W?

5/4W threw me off totally although I thought it might be 5W/4..

Thanks,

I guess the reference answer in the question bank is wrong. Spotted several errors already.

If it is dependent, then the answer will come directly from the combined rate given.
If it is independent, then agreed, answer will be 12.
