21. Anand and Bimal have to finish a certain job together. If Anand , working alone, can do the work in 25 days and Bimal is half as efficient as Anand, then in how many days will they finish the work?

• anand does in 1 day (1/25)
  whereas bimal does in 1 day (1/50)
  therefore both do in 1 day (1/25)+(1/50)=3/50
  so both complete the work in 50/3 days

• (1/A)+(1/(2A))=?
  1/A=1/25 given
  (1/A)+(1/(2A))=3/50
  so it will be done in 16.66 days.

• efficiency of anand=100/25=4%
  efficiency of bimal=4/2=2%
  together they finish in one day=6/100
  so total days=16.66days

• 1 day wrk of aand=1/25
  1............bimal=1/50
  they finish work in=1/25+1/50= 3/50
  i.e. 50/3=16.66 days

• anand does in 1 day (1/25)
  whereas bimal does in 1 day (1/50)
  therefore both do in 1 day (1/25)+(1/50)=3/50

• 10 years agoHelpfull: Yes(1) No(0)
• answer 50/3
• 10 years agoHelpfull: Yes(0) No(0)
• in one day they can do together (1/25)+(1/50)=3/50
  so then can do the entire job together in 50/3 days
