Directions for questions 1 to 3: Answer the questions based on the following information. Recently, Ghosh Babu spent his winter vacation on Kya kya Island.

The face values of ace, king, queen and jack are ten. For other cards the face value is the number on the card. Once the ‗player‘ picks a card from the deck, the ‗dealer‘ pays him the base amount. Then the ‗dealer‘ picks a card from the deck and this card is called the top card. If the top card is of the same suit as the base card, the ‗player‘ pays twice the base amount to the ‗dealer‘. If the top card is of the same colour as the base card (but not the same suit), then the ‗player‘ pays the base amount to the ‗dealer‘. If the top card happens to be of a different colour than the base card, the ‗dealer‘ pays the base amount to the ‗player‘. Ghosh Babu played the game four times. First time he picked eight of clubs and the ‗dealer‘ picked queen of clubs. Second time, he picked ten of hearts and the ‗dealer‘ picked two of spades. Next time, Ghosh Babu picked six of diamonds and the ‗dealer‘ picked ace of hearts. Lastly, he picked eight of spades and the ‗dealer‘ picked jack of spades.
