5 Women can paint a building in 30 working hours. After 16 hours work, 2 women decided to leave. How long will it take for the work to be finished.
(a). 24
(b).110/2
(c)18
(d).118/3
(e).None of the above

• 5 women completes work in 30 hour.
  hence 5 women 1 hour work = 1/30
  and 1 women 1 hour work = 1/5*30= 1/150
  in 16 hour 5 women work =(16*5)/150 = 8/15
  total work left = 1-8/15 =7/15
  let 3 women will take x hour more to do remaining(7/15) work.
  (7/15)150 70
  x = ---------- = -------
  3 3
  
  hence total time = 16+(70/3) = 118/3

• 5 women's take 30hr to complete the work
  after 16hr 2 women leave the work so remaining work hr of two womens=14*2=28hr
  remaining 3 women work 30hr without leaving work and the work leaved by two women is to be also completed by these 3 women which is 28hr work
  the share of one of three women will be= 28/3
  thus total time=30+28/3=118/3 hence option d

• e.none of these
  
  ans will be 70/3.

• 5 women completes work in 30 hour.
  hence 5 women 1 hour work = 1/30
  and 1 women 1 hour work = 1/5*30= 1/150
  in 16 hour 5 women work =(16*5)/150 = 8/15
  total work left = 1-8/15 =7/15
  let 3 women will take x hour more to do remaining(7/15) work.

  hence total time = 16+(70/3) = 118/3
• 9 years agoHelpfull: Yes(15) No(3)
• 5 women can paint a building in 30 hours
  so total woman work=5*30=150 woman hours
  for 16 hours 5 women work together so work done by 5 women=16*5=80 woman hours
  remanining work=150-80=70 woman hours
  70 woman hours of work can be completed by remaining 3 women in = 70/3 hours
  so total time taken for work=16+(70/3)=118/3 hours ans
• 9 years agoHelpfull: Yes(12) No(0)
• (d)
  1 women take time=30*5
  16 hours work done by one women will be 16*5
  after 16 hours time left to work for one women= 150-80=70
  if that left work will be done by 3 women then it will be done in 70/3 hour
  then total time= 16+70/3 = 118/3

  EXPLAINATION:
  5 women paints the wall in 30 hours
  1 women will paint in 5*30=150 hours
  3 women will paint in 150/3=50 hours
  after 16 hours work done by 5 womens will be:16x/30=8x/15
  remaining work is: x-(8x/15)=7x/15
  now this work has to be finished by remaining 3 womens
  time taken by 3 womens to finish the entire work is 50 hours so 7x/15 work part will be finished by them in:
  (50/x)*(7x/15)=70/3
  hence the total time taken by them to finish the entire work is:
  16+(70/3)=118/3
• 9 years agoHelpfull: Yes(6) No(3)
• total work= 5*30= 150 WH
  
  for 16 hrs, 5 women work, so W1= 16*5= 80 WH
  
  left work, W2= 150-80= 70 WH
  
  this work is completed by 3 women. let they take x hrs.
  
  so, 3*x= 70
  x= 70/3 hr
  
  hence total time = 16+70/3= (48+70)/3=118/3 hrs

• 5 women completes work in 30 hour.
  hence 5 women 1 hour work = 1/30
  and 1 women 1 hour work = 1/5*30= 1/150............>(1)
  in 5 women 16 hourwork =(16*5)/150 = 8/15
  total work left = 1-8/15 =7/15
  let 3 women will take x hour more to do remaining(7/15) work.
  3 women x hour work=7/15
  1 women 1 hour work=7/(15*3*x).........>(2)
  equate (1) nd (2),
  1/150 =1/(15*3*x)
  on simplifying, x= 70/3 hrs
  hence total time=16hrs + 70/3 hrs = 118/3
• 9 years agoHelpfull: Yes(3) No(0)
• (e)none of above
  16 hours work =16/30
  remaing work=14/30
  3 women work per hour=(1*3/30*5)=1/50
  work finished in hours=(14/30)/(1/50)=70/3
• 9 years agoHelpfull: Yes(2) No(5)
• my guess is none of the above.
  3 women works for entire 30hrs and 2 women works only for 16hrs.
  30/3 + 16/2 = x
  x=13

• 5wo----30hr----1 work.
  5wo----16hr----(16/30) work.
  remaining work=14/30=7/15.
  5wo---1work---30hr
  5wo---(7/15)work---{(7/15)*30=14hr}
  2wo---(7/15)work---{(14*5)/3=70/3hr}
  Hence, Total time=16+(70/3) hr=118/3hr

• the easiest ever..118/3
• 8 years agoHelpfull: Yes(1) No(1)
• after working 16 hours ,5 women can complete remaining work in 14 hours.
  so 14*5=3*h
  h=70/3
  total time is 70/3 +16=118/3

• Ans. c. 18
• 9 years agoHelpfull: Yes(0) No(7)
• more women:less days
  5/3=t/16
  so t=80/3

• Ans is a 24
  w 1 h work is 1/150
  5w 16 h work is 8/15
  Remain 7/15 done by 3 w in 24 hours
• 9 years agoHelpfull: Yes(0) No(6)
• e.none of dese
  ans:70/3
• 9 years agoHelpfull: Yes(0) No(5)
• answer will be none of the above
  work is= 5*30 women hours=150 women hours
  work done in 16 hours=16*5=80 women hours
  now work left=150-80=70 women hours
  now 70 women hours work is to be done by 3 women in "x" days
  =>70=3*x =>x=70/3
• 9 years agoHelpfull: Yes(0) No(4)
• this ques is very easy...refer r s agrwal.......
  more women -->less hours hence inversely proportional.
  After 16 hours.....the same task can be completed by 5 women in 14 hours
  and it is asked how many hours for 3 women.....
  hence it will be....
  5 *14=x*3 => x=70/3,,,,,one step answer hence option d
• 9 years agoHelpfull: Yes(0) No(0)
• 5w*30h=W
  16h*5+3*(x-16)=W=150wh
  =>x=118/3=39.33h

• 5 women completes work in 30 hours.
  Work done in 1 hour by 5 women=100/30(in %)=3.33%
  After 16 hours the work has been completed=16*3.33=53.28%
  Remaining works =(100-53.28)%=46.72%
  The remaining works has to be done by only (5-2=3) women, as two women decided to leave.
  Work done by a woman in 1 hour=3.33/5=0.667 %
  In a hour, the work can be done by 3 women=0.667*3=2.001%
  To acquire remaining works,
  hours=46.72/2.001=23.34 hours
  Total time to complete the work = 16+23.34=39.34
  39.34=118/3
