The ratio of efficiencies of Rahul and Ramesh to finish the same work is 4 : 5. Rahul worked alone for 8 days and then Ramesh joined him and worked for 16 days to finish the work. In how many days Rahul can finish the work alone?

• 4x*(1/8) + 5x=1/16
  (1/2)x+5x=1/16
  11x=1/8
  x=1/88
  FLIP Rule: x=88
  subsituting x=88
  4(88)*(1/8) ->44
  ans=44
