From given, A≥20, B≥15, C≥11, N = 25
the general formula : Total = A+B+C - (II) + (III) + N
At least one = Exact one + Exact two + Exact three = 25
At least one = A+B+C -(II) + (III) = 25 ---> 25 + (II) - (III) = A+B+C ≥ 46 ---> (II)-(III) ≥ 21
Exact two = (II)-3(III)
Exact three = (III)
To maximize "Exact one", "Exact two" should be = 0, and (III) is minimum
so if (II)-3(III) = 0 , then 2(III) = (II)-(III) ≥ 21 and (III) ≥ 10.5 ---> (III) = 11
Exact (1) = At least (1) - Exact (II) - Exact (III) = 25 - 0 - 11 = 14
