Jake can dig a well in 16 days. Paul can dig the same well in 24 days. Jake, Paul and Hari together dig the well in 8 days. Hari alone can dig the well in
option
A)48
B)96
C)24
D)32

• 1/x = 1/8 - (1/16 + 1/24)
  so x=48
  
  ans = 48 days
• 11 years agoHelpfull: Yes(34) No(2)
• jake=1/48 units per day
  paul=1/24 units per day
  ans:48
  jake+paul+hari=1/8
  1/48 + 1/24 + 1/x =1/8
  1/x=1/48
  so paul take 48 days to dig a well alone

• jake does 1/16 units per day
  paul does 1/24 units per day
  and they togethet does 1/16+1/24+1/x=1/8
  thus hari takes 48 days to complete

• efficiency of jake=6.25%
  efficiency of paul=4.16%
  efficiency of (jake+paul+hari)=12.5%
  so efficiency of hari=12.5%-(6.25+4.16)%=2.09%=48days answer(a)

• Let the total work to be done is 48 meters. Now Jake can dig 3 mts, Paul can dig 2 mts a day. Now all of them combined dug in 8 days so per day they dug 48/8 = 6 mts. So Of these 8 mts, Hari capacity is 1 mt.
  So he takes 48 /1 = 48 days to complete the digging job

• @SAURABH KUMAR VERMA
  sorry its a typing mistake
  jake = 1/16 units per day
• 11 years agoHelpfull: Yes(1) No(0)
• total days jake and paul took =1/16+1/24
  =5/48
  now,now hari dig the well alone= 1/8-5/48
  = 1/48
  ans= 48 days
• 11 years agoHelpfull: Yes(1) No(0)
• Jake and Paul work per day =((1/16)+(1/24))
  
  Three joined together to complete =in 8 days
  So (1/16)+(1/24)+(1/X)=(1/8)
  
  By re arranging we can get X = 48
  Which is the days required by the Hari to dig alone

• 1 day work of Jake = 1/16 = j
  1 day work of Paul= 1/24 = p
  1 day work of jake paul and hari = 1/8 =q
  1 day work of hari = q-(j+p) = 1/48
  Time taken by hari = 48 days

  explain how jake is 1/48?
• 11 years agoHelpfull: Yes(0) No(0)
• A.
  
  =1/8 - 1/24 - 1/16
  =1/48
  so 48.

• If Jake do work in 16days then Jake's one day work is 3.
  If Paul do work in 24 days then Paul's one day work is 2.
  If all three work together in 8 days then their one day work is 6.
  J+P+H = 6
  Substitute one day work of Jake and Paul , then
  H= 6-5 = 1
  Hence Hari one day work is 1 , So Hari took 48 says to complete the same work alone

• jack = 1/16 and paul=1/24
  jack + paul+hari= 1/8
  1/6+1/24=5/48
  1/8-5/48=1/48 hence answer is 48 days

• Jake can dig well in 16days
  Paul can do it in 24 days
  Jake, Paul and hari have done the work in 8 days
  So for 8 days jake, paul and hari are doing the work.
  Jake can do work in 16 days so he completed half of the work in 8 days=1/2
  lly, paul done 1/3
  1-1/2-1/3=1/6 this was done by hari in the span of 8 days so to do complete work 6*8 = 48 days
