21. B alone can do piece of work in 10 days. A alone can do it in 15 days. If the total wages for the work is Rs 5000, how much should B be paid if they work together for the entire duration of the work?
option
a) 2000
b) 4000
c) 5000
d) 3000

• ans:3000
  B in 1 day=1/10
  A in 1 day=1/15
  A+B in 1 day=1/10+1/15=1/6
  now B's share=(1/10)/(1/6)*5000=Rs.3000

• SORRY I READ THE QUE WRONG IT WILL BE ::
  THEY DO WORK IN 2:3 RATIOS
  2X+3X=5000
  X=1000
  A IS PAID A SUM OF 2000
  B IS PAID A SUM OF 3000

• i think b is paid with the amount of 3000 rs
  a->10 days
  b->15 days
  total work done in 6 days
  a's 1 day work is 3 units of the total 5 units
  b's 1 day work is 2 units out of 5 units
  -> 3X+2X=5000
  b paid 3000 rs

• THEY DO WORK IN 3:2 RATIOS
  3X+2X=5000
  X=1000
  A IS PAID A SUM OF 3000
  B IS PAID A SUM OF 2000

• ANSWER:Rs 3000
  let Rsx be paid to B
  15/10=x/(5000-x)

• Ratio of work done by A to B= 10 : 15=2 : 3
  Total wages= Rs 5000
  So A's share is 5000*(2/(2+3))=5000*(2/5)=Rs 2000
  So B's share is 5000*(3/(2+3))=5000*(3/5)=Rs 3000

• b's share 60%
  5000*60/100=3000

• the ratio of work done by A&B is 10:15=2:3
  so then the total amount divided to a and b would be 3000 and 2000 since a is doing in 10 days it would get more money or else 3/5*5000 gives the required answer:3000

• work ratio (10:15) ....so it is 2:3
  now wages ratio (3:2) so total work is 5 (from the ratio we get that 3+2 =5) Now total wages is 5000...so according to the ratio B will get 3000 even if they work together...

• (B+C)'s 1 day work= (1/10+1/15)= 5/30
  so B+C together take 30/5 =6 days to finish the work.
  
  Now, for 10 days work B gets = rs 5000
  therefore for 6 days work he will get= (5000/10)*6 = rs 3000 (ans)
