ans is green...
yellow box can have either of pink/yellow balls.
if we put a yellow ball in "yellow" box then it wud imply that "yellow" is also the colour of the box which has the red ball(becoz acordin 2 d question,d box of the red ball n the ball in the yellow box have same colour)
thus this possibility is ruled out...
therefore the ball in yellow box must be pink,hence the colour of box containin red ball is also pink....
=>the box colour left out is "green",,,which is alloted to the only box left,,,the one which has yellow ball..

The formula is p(a union b)=p(a)+p(b)-p(a intersect b)
so, according to our problem p(a union b )=40 p(a)=30; p(b)=20;
so, we have to find p(a intersect b), so=30+20-40 =10prititripathi
