Hey im a bit confused because doesn’t the stem say that >55% produced in SECOND factory so S1 tells us that X1 produced in second factory because if it was produced in first it would become 11/20 which would make Factory 2 less than 55%? Just trying to understand the justification provided because I interpreted the stem as the opposite of the explanation you gave here it seems haha
I agree , it says >55% of total units (20) > 11 was produced in second factory so, if first factory is already producing 8 items , it cannot produce X1(3) as it would make it 11(55%) .
In the second statement, 9 items are already produced in 2nd factory so inorder to make it >55 % either X1,X2 or X6 can be produced in 2nd factory, not sufficient.
Only statement 1 is sufficient to answer whether X1 is produced in 1st factory or not, so the answer should be A
