From New Scientist #1213, 7th August 1980 [link]
Three pairs of brothers went off or a day’s fishing and each pair caught the same number of fish between the two of them. Anglers are not everyone’s first choice for guardians of truth, however, and the table above needs a pinch of salt. It records what each man (listed down the left) claimed that three men (listed across the top) had caught. (For instance, Charles claimed that Bert had caught 11). To sort it out, you need to know that each always states his brother’s catch correctly but overstates his own and understates anyone else’s.
Who really caught how many?
