Answer 2

Answer:

Hi!!

Step-by-step explanation:

How many such machines are required = x;

Assume this chain rule formula,

(machine1 * timetaken by machine1) / workdone by machine1 =

(machine2 * timetaken by machine2) / workdone by machine2.

by substituting the given values,

(1 * 3) / 50 = (x * 6) / 300.

x = (1 * 3 * 300) / 6 * 50

  = 900 / 300

which is equal to 3 machines required
