A 14.4 kg gas cylinder runs for 104 hours when the smaller burner on the gas stove is fully opened while it runs for 80 hours when the larger burner on the gas stove is fully opened. Which of these values are the closest to the percentage difference in the usage of gas per hour, between the smaller and the larger burner?

• capacity of the gas cylinder=14.4kg
  smallar burner consumes gas=14.4/104=0.1384kg per hr
  larger burner consumes gas=14.4/80=0.18kg per hr
  difference in the usage=0.18-0.1384=0.0416 kg per hr
  so percentage diffrence=(0.0416/0.1384)*100=30.05% or 30%.

  percentage of smaller burner=0.1384/0.3184=43.4%
  percentage of larger burner=0.18/0.3184=56.5%
  so percentage difference=13%
