Question 18
The number of pairs of red socks, the number of blue socks and the number of white socks Mr. Zack has are consecutive even numbers respectively. He always puts all of his socks in a box. It is known that when blinded, he has to take out 26 socks to make sure that he has exactly 1 pair of white socks. How many socks does he have in total? (The right sock is different from the left one and all the socks are paired).
Editorial grading convention: 26 is the minimum number of draws guaranteeing at least one white left-right pair. A white left sock can pair with any white right sock. Keep the printed distinction between red pairs and blue/white individual socks.
