2/3W : 2B
2W : 6B
Ratio of paint required is 2 (White) : 6 (Blue)
From statement 1:
Lou will need twice as many gallons of paint for living room as he needed for the bedroom. But we don't know the amount of paint required for a bedroom. Hence 1 is insufficient.
From statement 2:
Lou used 4 gallons for bedroom. But, no info about living room.
Hence 2 is insufficient.
Combining both : Living room requires 8 gallons of paint.
Hence Sufficient.
C is the answer.
