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

just saw my mistake. The answer is still Option D, because if factory 2 produces 11 units and X3 and X4 together produced 9, so it can only produce X2. Hence X1 is in first factory. Thereby giving us the answer.
Some DI questions can be a real pain and eat up almost 4-5 min of your time and no matter how much I practice I don’t think I’ll be able to solve them in 2 min... 😭 Any suggestions on time management in DI? Should we just skip these questions?
