if it takes 6 printing presses 4 hours to print 5000 newspaper how long shoul it takea 3 presses to print 3000 newspaper

• (6*4)/5000=(3*x)/3000
  ==> 24/5000=3x/3000
  ==> x=(24*3000)/(5000*3)
  ==> x=24/5
  ==> x=4.8 ans

• 6machines → 4 hrs → 5000 papers......Then [6/2 = 3] machines → 4*2=8 → 5000 papers...Then 3000 papers will take [(8*3)/5]= 28/5 = 4.8 hrs = 288 mins = 4 hrs and 48 mins

  machine: 3:6 }
  newspaper:5000:3000} = 4:x so 4*3*5000/3000*6,x=4.8 hr

• (6*4)/(3*h) = (5000)/(3000);
  
  h = 24/5;
  
  h = 4.8 hours

• let n be the hours
  then from formula n1.d1.w2=n2.d2.w1
  =>6*4*3000=n*3*5000
  =>n=72000/15000
  n=4.8

• 6 printing 4 hrs 5000 nsp
  3 printing x hrs 3000 nsp
  6*4/(3*x)=5000/3000
  x=4.8hrs
  4hrs 48 min

• 6 printing press takes 4 hours to print -> 5000 newspapers
  1 printing press takes 24 hours to print ->5000 newspapers
  3 printing press would take 8 hours to print ->5000 newspapers
  So,
  Now we see,
  It takes 8 hours to print -> 5000 newspapers
  So, it takes (8/5000)hrs to print -> 1 newspaper
  and for 3000 newspapers, it would be
  ((8/5000)*3000) hrs to print ->3000 newspapers.
  
  Ans. 4.8hrs
