Two machines are monitored for their efficiency. Machine A puts out 250 J of work for every 800 J of work put into the machine. Machine B provides 500 J of work for every 1200 J placed into the machine. Which machine is more efficient?
A. Machine B
B. Machine A
C. They are equal

Answer 1

Machine B

Step-by-step explanation:

Efficiency of Machine A =
`(250)/(800) = 0.3125`

Efficiency of Machine B =
`(500)/(1200) = 0.4167`

Hence machine B is more efficient

Hopefully this answer helped you!!
