Answer 1

Answer:

One machine fills 300 bottles in 4 hours, so it fills 300/4=75 bottles in 1 hour. You have 6 machines so each hour you are filling 75 x 6=450 bottles. The number of hours required to fill 9000 bottles is 9000 divided by the number of bottles you fill in 1 hour, so 9000/450 =20

A machine can fill 300 bottles in 4 hours. How much time will be required for six such machines to fill 9000 bottles?

One machine fills 300 bottles in 4 hours.

So, in one hour, no. of bottles it fills = 300/4

= 75 bottles.

Therefore, no. of bottles, six machines fills in 1 hour = 75 × 6

= 450 Bottles.

The number of hours required to fill 9000 bottles by the six machines = 9000 / 450

= 20 hours.

Hence, we've got the required answer!

Hope it helps you, dear! ❤☺✌❤
