    Q6) Sanaa and Pallavi had a row over the distribution of a box of chocolates that was given to them by their friend, Danish. Pallavi yelled, "You haven’t distributed the chocolates fairly! You have kept thrice the number of chocolates that I have, for yourself. I demand a re-distribution!" To this, Sanaa calmly responded by giving Pallavi one chocolate for each year of her age, in addition to what she already had and asked, "Are you happy now?". "This is still unfair! Now, I have half as many chocolates as you do", screamed Pallavi. Sanaa lost her cool and yelled back, "Listen, I think I've given you more than enough. After all, I'm twice your age. You have to obey me." Saying this, she stormed out of the room, leaving all the chocolates, including her own, on the table. After she left, Pallavi took her own chocolates and stole chocolates from Sanaa's pile equal to Sanaa's age and ran away. Sanaa later came and collected her chocolates that were left on the table.

    Q9) There is a colony in which each person knows how to speak in one or more of the three languages Dothraki, Elvish and Parseltongue. It is known that the number of people who speak only Dothraki, the number of people who speak only Elvish and the number of people who speak only Parseltongue form an arithmetic progression. Similarly, the number of people who know exactly two languages also form an arithmetic progression. The number of people who know all the three languages is one-tenth of the number of people who know only Elvish, which in turn is two-thirds of the number of people who know only Parseltongue. The number of people who know both Dothraki and Elvish is 15 and the number of people who know both Elvish and Parseltongue is 19. The number of people who know to speak in Parseltongue is 70 and the number of people who know how to converse in Dothraki is fewer than that.

    1. What is the sum of all the values of the total number of people in the colony that could be possible?

    2. How many people can converse in Dothraki and Parseltongue?

    3. What is the maximum possible number of people who can understand Dothraki?

    4. What is the number of people who know at least two languages?
