Percentage Distribution:

30 Dark Chocolates

25 Milk Chocolates

20 Taffy

5 Caramel

20 Cream

Number of candy per box = 20

Number of boxes = 80

Total number of candies = 80 x 20 = 1600

Number of Taffy = 20/100 x 1600 = 320

Rest of the lot is 1600 - 320 = 1280

So if he picks 1280 candies, there is a possibility that it doesn't include a Taffy!

But... if he picks 1281 candies, there must be atleast 1 Taffy in it!

So ans: 1281

Yes, but the question say: What is the maximum number of candy pieces a quality control inspector can open

before coming across a taffy candy. - This number is 1280 in my eyes.
