A can do a particular work in 6 days . B can do the same work in 8 days. A and B signed to
do it for Rs. 3200. They completed the work in 3 days with the help of C. How much is to be
paid to C?
A. Rs. 380
B. Rs.
600
C. Rs. 420
D. Rs.
400

• Amount of work A can do in 1 day = 1/6
  Amount of work B can do in 1 day = 1/8
  Amount of work A + B can do in 1 day = 1/6 + 1/8 = 7/24
  Amount of work A + B + C can do = 1/3
  Amount of work C can do in 1 day = 1/3 - 7/24 = 1/24
  work A can do in 1 day: work B can do in 1 day: work C can do in 1 day
  
  = 1/6 : 1/8 : 1/24 =4:3:1
  Amount to be paid to C = 3200 * (1/8) = 400

• A's one day wage=3200/6
  He worked for three days, his share=1600
  B's one day wage=3200/8
  His share for three days=1200
  C's share=3200-(1600+1200)=1200
  i.e for 3 days
  C's one day share=400

• A&B=1/6+1/8=7/24 in 1 day
  
  work done by a&b in 3 days=3*7/24=7/8
  
  c'share=1/8*3200=400

• 1/a+1/b+1/c=1/3
  1/c=1/3-(1/6+1/8)
  1/c=1/24
  it means c needs 24 days to complete the whole work
  total amount=3200
  and c works for 3 days
  (3/24)*3200=400

• a=1/6 , b=1/8 , c=1/x.......
  1/6+1/8+1/x=1/3...
  x=24
  than a:b:c=1/6:1/8:1/24
  taking lcm,than we get..
  4:3:1
  for c=3200/8 = 400rs ....ans.
