umka2103 [35]

Answer:

30 parts

Step-by-step 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 = $\frac{40}{2}=20 minutes$

Machine A and machine B produces parts at constant rate.

Machine A produces parts at the rate= $\frac{100}{20}=5 parts /minute$

In one minute,Machine A produces =5 parts

In 6 minutes , machine B produces = $5\times 6=30$ parts

Hence, machine A produce parts in 6 minutes=30
