Question

Machine A produces 100 parts twice as fast as Machine B does. Machine B produces 100 parts in 40 minutes. If each machine produces parts at a constant rate, how many parts does Machine A produce in 6 minutes?

Answer 1

30 parts

Explanation:

We are given that machine produces 100 parts twice as fast as machine B does.

Machine produces 100 parts in 40 minutes.

We have to find number of parts produces by machine A in 6 minutes.

According to question

Machine A takes time to produce 100 parts =
`(40)/(2)=20 minutes`

Machine A and machine B produces parts at constant rate.

Machine A produces parts at the rate=
`(100)/(20)=5 parts /minute`

In one minute,Machine A produces =5 parts

In 6 minutes , machine B produces =
`5* 6=30` parts

Hence, machine A produce parts in 6 minutes=30
