If 5 persons can do 5 times of a work in 5 days, then 10 persons can do 10 times of that work in

• w1/w2 = (m1d1t1)/(m2d2t2)
  5/10 = (5x5)/(10xd2)
  therefore number of days equal to 5 days
  5 days

• 5 days
  
  5 persons, 1 time work, in 5/5= 1 day
  10=5*2 persons, 1 time work in 1/2 days , So
  10 persons , 10 time work in 10*1/2=5 days

• more persons, less days(indirect proportion)
  more work ,more days(direct proportion)
  persons 10:5} : 5:x
  work 5:10 } :
  x=5days

• work = Time * persons
  if the work and persons are increased by same proportion then the change in the time is constant.

• person time amount of work
  1) 5 5 days 5x (let work be x)
  2) 10 t 10x
  
  (persons*time)/work
  i.e. (5*5)/5x=(10*t)/10x
  therefore t=(5*5*2)/10
  t=5 days.
