Making equation let A for Apple, B for Banana and G for Grape,

A + G + 2B = 210

ans condition is B =< G =< A

range is [ 30, 90 ]

So total possible solutions which staisfies the condition and equation both will be 6

(1) A = 90 , B = 30 , G = 60
(2) A = 80 , B = 30 , G = 70
(3) A = 90 , B = 40 , G = 40
(4) A = 80 , B = 40 , G = 50
(5) A = 70 , B = 40 , G = 60
(6) A = 60 , B = 50 , G = 50

Some cards from an ordinary pack of playing cards were laid out on a table with face upwards. I thought of one card there, The KING OF HEARTS. I announced that I would tell Mr. A the value and Mr. B the suit of my chosen card. I whispered to Mr. A that I had chosen a KING and whispered to Mr. B that I had chosen a HEART. Their subsequent discussion went as below:

A: “I do not know the card that was chosen”

B: “I knew you would not”

A: “I still do not know the card, but at least I can now work out its colour”

B: “Now at last I can work out what card it is”

A: “So can I”
