Used to be like that in Norway. Some older people will still say "two-and-forty", "eight-and-seventy", instead of "forty-two", "seventy-eight", etc.

In 1950, the gov. decided that it was time to standardize things - and the catalysator for this was actually the phone switching centrals/boards, that argued having one standard method would decrease errors in the manual patching. Remember, back in the day you had human operators that would operate the switching boards.

This change was called "The new counting method", and describes how numbers between 20 and 100 are counted/pronounced.
