Q. Colorful Pain Company contracts to paint three house. Mr. Brown can paint a house in 6 days, while Mr. Pink would take 8 days and Mr. Blue would take 12 days. After 8 days Mr. Brown goes on vacation and Mr. Pink begins to work for a period of 6 days. How many days will it take Mr. Blue to complete the contract?

• brown works for 8 days=> work done by him=8(1/6)
  pink works for 6 days => work done by pink=6(1/8)
  let blue works for 'x' days=> work done by him =x(1/12)
  total work => 3=8(1/6)+6(1/8)+x(1/12)
  x=11
  blue takes 11 days

• 2 days , because the part of the work that was being completed by brown & pink = 17/18
  still 1/18th part must be completed which will be completed by blue in 2days
