Combinations for different rows will be, 14 - 8, 12 - 9, 0 - 15, 2 - 14.
Given in the question,
- Total number of people = 60
- Number of players who can play chess = 2
- Number of players who can play Uno = 4
Let the number of chess games played = x
And number of Uno games played = y
Therefore, equation for this situation will be,
2x + 4y = 60
For the 1st row given in the table,
If y = 8,
2x + 4(8) = 60
2x = 28
x = 14
For the 2nd row of the table,
If x = 12,
2(12) + 4y = 60
4y = 36
y = 9
For 3rd row of the table,
If y = 15,
2x + 4(15) = 60
x = 0
For 4th row of the table,
If x = 2,
2(2) + 4y = 60
4y = 56
y = 14
Therefore, combinations for different rows will be, 14 - 8, 12 - 9, 0 - 15, 2 - 14.
