Answer:
you have accounted for 12+7+11+6 pills = 36 pills
so that leaves 60-36 = 24 pills that have two vitamins.
since there are the same number with each of the other three possibilities, that means there are 8 pills that are A&B and 8 that are A&C.
so the # pills that have vitamin A are:
A only = 12
A&B = 8
A&C = 8
A&B&C = 6
total = 34 pills that contain vitamin A
