Cards
Written on 5:11 pm by Vja Students
9 cards are there. U have to arrange them in a 3*3 matrix.Cards are of 4 colors.They are red,yellow,blue,green.
Conditions for arrangement:
One red card must be in first row or second row.
2 green cards should be in 3rd column.
Yellow cards must be in the 3 corners only.
Two blue cards must be in the 2nd row.
At least one green card in each row.
Solution:
Yellow Red Green
Blue Blue Green
Yellow Green Yellow
The cards could be arranged as follows
|R G Y|
|G B B Y|
|G G Y|
But, it is impossible to arrange the 2nd row satisfactorily, because the rules suggest that there would be three cards in the 2nd row, but on the other hand, the rules say that there must be One Yellow card at a corner of the row, One Green card compulsorily in each row and a special case of two blue cards in the second row. That makes a total of 4 cards in the second row of 3. Sorry. No solution.
Here you go...
----------
Y | R | G |
B | B | G |
Y | G | Y |
