A)24 B)36 C)30 D)45

• I solved this without pen&paper.They worked together for 12 days remaining 6 days work can be completed by Akash in 10 days. If u consider akash is alone can complete the work..so,
  6------>10
  18---->?
  =180/6=30

• A ans S together complete 1/18 work in one day
  They work for 12 days so they complete 12/18=2/3 part of work
  Remaining 1/3 part of work akash alone completed in 10 days so,
  1/3 work= 10 days
  1 work=30 days

• A+S=1/18
  (A+S)12+A(10)=1
  (1/18)*12+A(10)=1
  A(10)=1/3
  A=30
