1The question is very badly worded. Apparently the statement ‘$a_2$ number of fishermen caught at least two fish among them’ is supposed to be interpreted as ‘there were $a_2$ fishermen who each caught at least two fish’, though in standard English it actually means something quite different, namely, that there was a group of $a_2$ fishermen whose combined catch was at least two fish. With that reinterpretation this does become the linked question, which is correctly stated. In this version the question is more a matter of guessing the author’s intent than of working out the mathematics. – Brian M. Scott Jun 19 '20 at 17:31
