**Answer :**

From 1 & 2,

we know that Green is one of the ball.

and blue is not one of the ball.

From this info and 3,

we know that green and purple are the 2 balls.

So,

Green is placed in last position (since it cannot be placed in 1st or 2nd)

Now If purple is placed in 2nd position, then there are 2 possibilities,

the third ball is either yellow or red, and placed in 1st position,

but from 1 and 2, neither red or yellow can be placed in 1st position.

So purple is placed in 1st position, and the third ball is either red or yellow

and placed in 2nd position,

Now suppose the 3rd ball is red but it cannot be placed in 2nd position (see 2)

So the third ball has to be yellow and placed in 2nd position.

So the order of the balls is

**Purple : Yellow : Green**
