A,B and C can do a piece of work in 4,5 and 7 days respectively. They got $415 for the job. what is A's share?

• Rs. 175
  
  Share of A,B and C is divided in ratio of
  
  1/4 : 1/5 : 1/7
  or
  35:28:20
  
  A's share = 415 *35/ 83 = Rs. 175.

• 1/4+1/5+1/7=83/140 (work done per day)
  So amount will be divided in multiples of this share.
  
  for 83/140 they get $415
  
  So for 1/4 work A gets, 1/4*140/83*415 = $175
  So for 1/5 work B gets, 1/5*140*83*415 = $140
  So for 1/7 work C gets, 1/7*140*83*415 = $100
