one man can do a piece of work in 10days. one boys join him & he complete the work in 6days . if he gets 50rs for his work then what will be the share of the boy.

• 20 Rs.
  1 day work of Man=1/10, If Boy's 1 day work=1/x, then
  (1/10)+(1/x)=1/6, x=15
  Ratio of work of Man & Boy=1/10:1/15=3:2
  So out of 50 Rs. Boy's share=2*50/(3+2)=20

• 20 is the wrong answer.
  
  50 rupees is not toatal share..its only share of 1st persion. findout the total share , and then use 2/5*total share.

• 20.
  Let boy complete work in b days.
  Man one day work 1/10
  Boy one day work 1/b
  So the equation form
  (1/10) + (1/b) = (1/6)
  From this b = 15days
  Work done in one day is in 3:2 proportion so boys share is 20.

• M = 1/10,M+B = 1/6 SO B=1/6-1/10=1/15
  SO M:B = 2:3
  Boys share is 3/5*50 =30RS

• 20 Rs.
  man can do work in 10 days
  man + boy can do a work in =6 days
  so work done by man in 1 day is 6
  and work done by boy in 1 day is 4.
  so share of boy will be (4/10) * 50= 20 Rs.
