HCL prototyping machine can make 10 copies every 4 seconds. At this rate, How many copies
can the machine make in 6 min.?
a) 900
b) 600
c) 360
d) 240
e) 150

• a)900
  
  10 copies--4 sec
  10/4 copies--1 sec
  (10/4)*6*60---1*6*60 sec
  900 copies--6 min

• 4 sec-10 copies
  60 sec(1 min)-150 copies
  For 6 min, 150*6 =900 copies

• 4 sec. =10
  60sec = 10*60/4
  6 minute = 10*60*6/4 = 900

• answer is a) 900.
  solution is:-
  10 sec=4 bottles
  
  now, 6 min=360 seconds
  360/4 = 90 times
  90 * 10=900 copies

• 10 copies-->4 sec
  so,6 min means 6*60=360 sec .....
  for 4 sec 10 copies .then 360 sec means 360/4=90
  for 90*4=360
