Q. In a hospital there are 120 open heart surgeries and 199 stone surgery in a week. A doctor can do atleast 1 and atmost 3 open heart surgery in a week and atleast 2 and atmost 3 stone surgeries in a week.what is the difference between the max and min number of doctore required to do so.

dnt knw the exact questn.anybody knw exact questn plz post it.

• 120 open heart surgeries needed 120 doctors because a doctor can handle only 1 heart surgery at a time(*consider only atleast now)
  so that 120 doctors are enuf to do the stone surgery too.
  Max. No. of doctors=120
  Now take atmost.
  40 doctors are needed for heart surgery.
  and for stone surgery 67 doctors needed(67*3=201)
  so Max-Min=120-67=53;

• minimum number of doctors required =67
  maximum number of doctors can not be 120,because each doctor has to do a minimum of 1 heart surgeries and minimum of 2 stone surgeries per week.so we have to consdier the maximum of those two.
  i.e,if we consider maximum doctors are 120,then they must do a minimum of 240(120*2)stone surgeries.But here only 199 stone surgeries are happening.
  So maximum num of doctors reqd is 99(199 stone surgeries=98*2+1*3)
  so the diff is 22(99-67)

• Answer: Max=99 Min=67
  Solution:
  Doctors can perform 120 OHS and 199 SS in a week.
  For Max:
  if atleast 1 doctor should perform an OHS. SO 120 doctors are needed for OHS.Now when these 120 doctors perform atleast 2 SS so total they will perform 240 SS but only 199 SS they can perform in a week. Hence we check for SS i.e. 199/2=99. Hence max of only 99 doctors are needed.
  For Min:
  199/3=67 hence only 67 doctors are needed.

  and minimum no. of doctors needed=67;
  so 120-67=53

• for ops possble no will be1,2,3/
  and fo stone srgry....it wll be 2 or 3..
  so for maximum no of doctor..one doc. will do only one ops..i.e 120 doc will be required as they (120)also able to do all stone surgry also...
  ;
  for minimum no of doc..take case(3,3)..
  so for ops 120/3=40 doc will be required..
  for stone these 40 will do max 40*3=120 stone surgry..
  so remaining stone surgry..199-120=79 ..this wll requre min of 27 docas 79/3=27 tking all srgry to be done..
  so total doc..
  40+27=67
  diff..
  120-67=53...

• if we take total surgeries to be 120+199=319 and sum total that a doctor does atleast 3 and atmost 6 surgeries in a week then 319/3=106(app.) and 319/6=53 then max-min=106-53=53 ans.
