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
a. 96 days
b. 48 days
c. 32 days
d. 24 days

• jake 1 day work=1/16
  paul 1 day work=1/24
  j+p+h 1 ady work=1/8
  1/16+1/24+1/x=1/8
  1/x=1/48
  x=48
  so,Hari alone can dig the well in 48 days

• ANS IS :48
  LCM OF 16,24=48
  TOTAL UNIT WORK IS=48
  JAKE=48/16=3
  PAUL=48/24=2
  JAKE+PAUL+HARI=48/8=6
  3+2+HARI=6
  5+HARI=6
  HARI=1
  HARI ALONE CAN DIG THE WELL IN 48/1=48 DAYS

• let us assume that x be the days taken by hari.jake can done in 1/16,paul can done in 1/24,
  J+P+H=1/8
  1/16+1/24+1/x=1/8 then by solving we get x=48

• Simple one. 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.

• hari=1/8-(1/16+1/24)=1/8-5/48=6-5/48=1/48
  48 days he can do.

• simple find lcm of 24,16,8 find one day work and then find
  and simple 48 days

• let it be x days for Hari to complete the task
  => (1/x) = (1/8) - (1/16) - (1/24)
  => (1/x) = (1/48)
  reciprocating the values x= 48
  So, Hari alone can complete in 48 days

• (b)
  one day work of jake is 1/16
  one day work of jake is 1/24
  one day work of jake is 1/x

  l.c.m of(16,24)=48
  j per day=48/16=3unit
  p per day=48/24=2unit
  j+p+h 1day=48/8=6 unit
  so h=6-(3+2)=1unit per day

• 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.
