Alphabetical Number

Monday 4th May 2015

The puzzle for this month is not, on the surface, strictly mathematical but, as you’ll see from the answer at the end of this newsletter, there is some mathematical debate as to the correct answer. It is however a puzzle that can keep you thinking throughout the day and keep your mind active during coffee breaks, jogging sessions or when the output of the TV is not really very engaging.

Here it is. Find the number which when written as a word has all the letters in alphabetical order and then find the first number to contain the letter A.
