15 Java programmers, working in a constant pace, finish a web page in 3 days. If after one day, 9 programmers how many more days are needed to finish the remaining job ?
(a) 2 (b) 4 (c) 5 (d) 6

• 15 programar 3 days work=1
  
  1 programar 1 day work=1/(3*15)=1/45
  15 programar 1 day work=15/45=1/3
  
  remainder work=2/3
  9 programar 1 day work=9/45=1/5
  so,
  9 programar 1/5 work= 1day
  9 programar 1 work=5day
  2/3work=5*2/3
  =3.3days=4days
  hence ans is 4 days

  The best answer is c.
  The total working days for finishing a web page are (15 x 3) 45. If after one day 9
  programmers quit, only 15 working days are done and the rest of the programmers (6)
  Need to finish (45 – 15) 30 days of work. It will take them 5 more days.

• 15 workers complete in 3 days..
  so man*day=constant
  15*3=45 man.day
  now 1 day and 15 workers so
  1*15=15 man.day
  so left man day 45-15=30 man.day
  now 6 man left so,
  6 man*day=30 man*day=5 days
  now total days 5+1=6 days
  ans=6
