Four firefighters were discussing the number of fires they extinguished for the month of February. Rafael extinguished 25% fewer fires then Louis in February. William extinguished 50% more fires then Rafael. Albert extinguished 20% fewer fires then Rafael and William combined. If Louis extinguished 6 fires per week, how many fires did all four men extinguish during the entire month?

It is 105 – I will explain the rationale!
Assuming it is not a leap year.

Louis = 4 x 6 = 24
Rafael 24 x 75% = 18
William 18 x 150% = 27
Albert = 80% x (18+27) = 80% x 45 = 36

24+18+27+36 = 105
