A sum is sufficient to pay either George age for 15 days or marks wage to 10dayshow long together?

• George one day work is (1/15)
  Marks one day work is (1/10)
  G+M=(1/15)+(1/10)=(1/6)
  6 is the answer

• george work 1/15
  marks work 1/10
  work together so (1/15)+(1/10)=(1/6)
  then 6 will be the answer

• Ans=6days
  Total work= Geroge and marks is 60 work. i.e LCM of Geroge and Marks
  now George does 2Work/day.
  marks does 3work /day
  if both work G+M=5work/day
  so total 30 work=30/5=6 days..

• consider sum is lcm(15,10) =30rs
  George one day 30/15=2rs
  marks one day 30/10=3rs
  total one day pay=2+3=5rs
  30/5=6 its sufficient for 6days

• george 1 day work is=1/15
  mark 1 day work is=1/10
  together=(1/15)+(1/10)
  =5/30
  =6
  because 6 is the answer

• f(2018)=f(2x1009)=f(504+1)=f(2x252+1)=f(252)+1
  f(252)=f(2X126)=f(126)=f(2X63)=f(63)=f(2X31+1)=f(31)+1
  f(31)=f(2X15+1)=f(15)+1
  f(15)=f(2X7+1)=f(7)+1
  f(7)=f(2X3+1)=f(3)+1
  f(3)=f(2X1+1)=f(2)+1
  f(2)=f(2X1)=f(1)
  f(1)=f(2X0+1)=f(0)+1=1
  
  So we have, f(1)=1
  f(2)=1
  f(3)=1+1
  f(7)=2+1
  f(15)=3+1
  f(31)=4+1
  f(252)=5+1
  f(2018)=6+1=7 Ans
