The lodge has fuel for 20 rooms heated for (14) days = 280 “fuel-days” of fuel. Fuel day is fuel required to heat one room for one day.
If the lodge only needs to heat 15 rooms instead of 20, divide 280 by 15 to get 18.666….
You are asked for FULL days, so round down to get 18.
So originally we had heated room for 14 days now we have 18. Hence there are 4 more days.
Hence option B is correct!

Thank you, you comfort me. I spent hours trying to understand why ManhattanPrep reported OA as D. We are asked EXTRA full days, not full days.
