Barrel of oil

Barrel of oil weighs 283 kg. When it mold 26% oil, weighed 216 kg. What is the mass of the empty barrel?

Correct answer:

m =  25.3077 kg

Step-by-step explanation:


m + o = 283
m + (1-26/100) o = 216

m + o = 283
m + (1-26/100)•o = 216

m+o = 283
100m+74o = 21600

m = 329/13 ≈ 25.307692
o = 3350/13 ≈ 257.692308
