Q. There are three boxes , In one box Two Red balls , In two box 2 blue balls In three box 1 Red & 1 blue. The labels on the boxes are not correct. Then you have to open one box and to find the colour of the balls in all boxes

• 1st box 2nd box 3rd box
  2 red 2 blue 1 red & 1 blue
  If we assume lables on the boxes are 1st box has 3rd box label ,2nd box has 1st box label nd 3rd box has 1st box label.
  If open any box we can know which colour is originally inside then automatically we can find the remaining two because the lables on the boxes shows wrong information

• There are three boxes , In one box Two white balls , In two box 2 black balls In three box 1 white &1 black
  The lables on the boxes are not correct.Then you have to open one box and to find the colour of the balls in all boxes.
  Solution: Open the box labled black& white If white balls are there then the box labled with white balls
  contain black balls and labled with black balls contain one black and one white ball and viceversa
  if two black ballsare there.

• Assume as follows
  box 1= 2 red balls and label= 2 blue balls
  box 2= 2 blue balls and label= 1 red 1 blue
  box 3= 1 red 1 blue ball and label= 2 red balls
  if we open box 1 then we can see red balls and as the labels on all boxes are wrong, we take the label correct label from box 3 and stick it to box 1 and interchange other two box labels because by keeping any label as it is we show that it is correct but its mentioned in the problem that all labels are wrong.
  
  lengthy info but i hope this helps

• open the box labelled 2blue balls and for sure you'll find either 2 red balls or 1 red and 1 blue ball.
  
  case1: you get 2 red balls
  the box labelled 2red balls wil have 1red+1blue and the other box will have 2 blue balls
  
  case2: you get 1red+1blue
  the box labelled 2 red balls will have 2 blue balls and 1red+1blue one will have red balls
  
  NOTE: as all the box are not labelled correctly.

• pick the box from which labeled mixed, it surely red or blue box
  if u get red(assume) then remaining box never be never be red and also both box written wrong
  blue box cant have blue balls or red balls so it has mixed ball.
  finally the leftover box is having colored balls.
