The power of diesel engine a is 1.5 times that of diesel engine B. the efficiency of diesel engine a is 20% and that of diesel engine B is 25% Is the answer 15:8 or 6:5 Although I calculated that it was 15:8, what's wrong with 6:5?

The power of diesel engine a is 1.5 times that of diesel engine B. the efficiency of diesel engine a is 20% and that of diesel engine B is 25% Is the answer 15:8 or 6:5 Although I calculated that it was 15:8, what's wrong with 6:5?

It's 15:8.1.5/20%, 1 / 25%. Power is divided by efficiency, not power multiplied by efficiency!

The power ratio of a and B diesel engines is 4:3, the efficiency of a is 40%, and that of B is 35
What is the ratio of fuel consumption per hour of the two diesel engines?

The fuel consumption per hour of two diesel engines a and B is respectively X and y
40%X / 35%Y=4/3
X:Y =(4 / 3) / (40% / 35%)
X:Y =7/6
A: the ratio of fuel consumption per hour of a and B diesel engines is 7 / 6

The power of diesel engine a is 1.5 times that of diesel engine B. the efficiency of diesel engine a is 20% and that of diesel engine B is 25%. The ratio of fuel consumption of diesel engine a to that of diesel engine B is 100 million per hour
The answer is 5:6. Why? The answer should be more specific. Please.

15:8
Set power a 150, B 100
Consumption a 750, B 400

The power of a is 1.5 times that of B. the efficiency of a is 20% and that of B is 25%. So the ratio of fuel consumption per hour between a and B is -?

Hello
Power ratio 1.5:1 = 3:2
Fuel consumption ratio (3 / 20%): (2 / 25%) = 15:8
