Sunday Times Teaser 2820 – Three Ages
by Andrew Skidmore
Published: 9 October 2016 (link)
Today is Alan’s, Brian’s and Colin’s birthday. If I write down their ages in a row in that order then I get a six-figure number. If I write down their ages in a row in the reverse order (ie, Colin’s followed by Brian’s followed by Alan’s) then I get a lower six-figure number. When I divide the difference between these two six-figure numbers by the total of their three ages the answer is Alan’s age multiplied by Colin’s.
What are Alan’s, Brian’s and Colin’s ages?
