Which of the following is true?       

I. Aaryan has White in box I so Ajay has either Yellow or Pink in box I. II. The sum of the number of colour of Ajay in box I and II is more than that in the box I and II of Aaryan so the box I and II of Ajay can carry either 18 or 19 total colour. Hence the box I and II of Aaryan can carry either 10 or 9 colour. III. As we know that Ajay has 9 yellow os Ajay can have either 8 or 9 Pink and Varun can have 9 or 10 Yellow. Further we know that the number of Pink with Ajay is less than the number of Yellow with Varun. In the similar manner we can eliminate other same colour box number or colour number.
