10 engines consume 80 litres diese
aume 80 litres diesel when each is running 9 hours a day. How much diesel will be required for Tu
bruinning 15 hours a day, whereas 6 engines of the farmer type consume as much as 5 engines of the
latter type?
Answers
Diesel consumed = 16n litres where n = number of engines running 15 hrs a day
Step-by-step explanation:
10 engines consume 80 litres diesel when each is running 9 hours a day
=> 80 litre Diesel is consumed in 90 hrs
=> in 1 hr Diesel consumed = 80/90 = 8/9 litre
6 engines of the former type consume as much as 5 engines of the
latter type
=> n engine of latter type will consume = n * 6 / 5 times Diesel
15 hrs a day
=> Effective number of hrs = 15 * n * 6/5 = 18 n hrs
Diesel consumed = (8/9) * 18n = 16n Litres
if Engines are 5 Then
Diesel consumed = 16 * 5 = 80 litre
if engines are 10 then
Diesel consumed = 16 * 10 = 160 litre
