Three friends Gerard, Runey and Ronaldo work together to dig a hole. Gerard alone can complete the work in 10 days and together all three can complete it in 4 days. They earn a total of Rs.1,200. Find the share of Runey if the money that they receive is proportional to the work that they do?
a)Rs 480
b)Rs 165.51
c)Rs 500
d)Rs 600

• the correct question is this : 3 friends Gerard, Rooney and Ronaldson work together to dig a hole. Gerard alone can complete the work in 10 days, Rooney in 8 days and together all three can complete it in 4 days. They earn a total of Rs. 1,200. Find the share of Rooney if the money that they receive is proportional to the work that they do?
  a. Rs.480 b. Rs.165.51 c. Rs.500 d.Rs.600
  
  and solution to this is : Ronaldson can complete work in 40 days ( ¼ - 1/10 -1/8)
  so ratio of work done is 1/10 :1/8 : 1/40 so the ration can also be written as 4 : 5 : 1
  so the amount payed rooney is 1200 * (5 / (5+4+1) ) which is equal to 1200 * 1/2 = 600
  
  Rooney share is 1200/2 = 600

• insufficient data...
  no information about runey and ronaldo's work.

• As no information about runey and Rinaldo's work is given so we would assume that they do work in equal ratio..... As gerard comletes 2/5 work in 4 days so
  Rest 3/5 work will be done by the rest two people in half half proportion.... Thus 3/10 work is done by runey in 4 days so he'll share 1200*3/10=360 rs

• gerard = 1/10
  rooney = 1/8
  ronaldo = ?
  all three can do the work in 4 days
  ronaldo work = 1/4 - ( 1/10 + 1/8 ) = 1/40
  ronaldo work = 1/40
  total money = 1200
  share = 1/10 : 1/8 : 1/40
  share = 4 : 5 : 1
  rooney share = 5/ (1+4+5) = 1/2
  rooney share in amount = 1200 * 1/2 = 600 rs

• Gerard's 4 day work=2/5
  left work=1-2/5=3/5 which is done by Runey and Ronaldo
  Gerard's share=1200*2/5=480
  TO Solve further either Runey or Ronaldo's work should be given

• ans is 480
• 9 years agoHelpfull: Yes(0) No(4)
• In 4 days runey will do 40% of work as he could do 100% of work in 10 days.. With that logic his share should be 40% which equals to 480rs

• Ronaldo can complete work in 40 days ( 1/4-1/10-1/8)
  So, ratio of work done = 1/10 :1/8 : 1/40 = 4 : 5 : 1
  So, amount earned = 1200 * (5 / (5+4+1) ) = 1200 * 1/2 = 600

• Here is the correct question:
  
  3 friends Gerard, Rooney and Ronaldson work together to dig a hole. Gerard alone can complete the work in 10 days, Rooney in 8 days and together all three can complete it in 4 days. They earn a total of Rs. 1,200. Find the share of Rooney if the money that they receive is proportional to the work that they do?
  
  A. Rs.480
  
  B. Rs.165.51
  
  C. Rs.500
  
  D.Rs.600
  
  Answer:
  
  Ronaldson can complete work in 40 days ( ¼ - 1/10 -1/8)
  
  So ratio of work done is 1/10 :1/8 : 1/40 so the ration can also be written as 4 : 5 : 1
  
  So the amount paid to Rooney is 1200 * (5 / (5+4+1) ) which is equal to 1200 * 1/2 = 600
  
  
  Rooney's share is 1200/2 = 600
