A & b can do total work in 18 & 24 days respectively. A starts work on the alternet days in how many days they the whole work completed

• On alternate day, it will take twice as much time taken to do work regularly. So work will finish in 34 days

• Work done by A per day=1/18
  Work done by B per day=1/24
  
  When they work together; A works only on alternate days, so the work done by him will be 1/18 divided by 2=1/36
  
  Hence the work done by both A and B,
  =(1/36) +(1/24) =5/72
  
  Therefore work will be completed in 72/5=15 days approx.
