Question: 3 similar lamps burn 4 gallon of oil in 100 hours. How much oil will 5 lamps burn in 60 hr?

I have struggled to find the answer
Clearly 5 lamps will burn more oil than 3, so the scale factor there is 5/3. Similarly since turning on a lamp for 100 hours will clearly burn more oil than for just 60 hours, the scale factor there is 60/100 = 6/10 = 3/5.
Hence the result is 4 gallons * 5/3 * 3/5 = 4 gallons * 1 = 4 gallons.
