We're given a few facts to work with:   1) The average height of the females is 170cm   2) The average height of the males is 181cm   3) The average of the GROUP is 180cm   We're asked for the RATIO of men to women.   W = number of Women   M = number of Men   (170W + 181M)/(W+M) = 180   170W + 181M = 180W + 180M   1M = 10W   M/W = 10/1   The ratio of men to women is 10 to 1.   10:1
