Arjun can complete 1/4th of a work in 10 days. Then Raj joins him and both of them complete the work together in 8 days. In how many days Raj alone finishes the work?

• arjun does a total of 1 work in 40 days
  or does 1/40 in 1 day
  while they both did 1/8 in 1 day thus raj's 1 day work would be
  1/8-1/40=1/10
  thus raj will finish the work alone in 10 days...
