No solution


Let the total number of balls is t.
We have:
b + y + r + p = t
Also we have:
14 = t - b
16 = t - y
24 = t - r
12 = t - p
Sum up the above 4 equations:
66 = 4t - (b+y+r+p)
66 = 3t
22 = t
The answer would be 22 but there is a contradiction where it say 24 balls are not red. It means the total should be greater than 24.
Considering the above there is no solution.
