The demand of different shirt sizes, as obtained by a survey, is given below:

Size	38	39	40	41	42	43	44
Number of persons (wearing it) :	26	39	20	15	13	7	5
Total = 125

7.5, 7.3m 7.2m 7.2, 7.4, 7.7, 7.7, 7.5, 7.3, 7.2, 7.6, 7.2

Find the mode of the following data in each case:

(i) 14, 25, 14, 28, 18, 17, 18, 14, 23, 22, 14, 18

(ii) 7, 9, 12, 13, 7, 12, 15, 7, 12, 7, 25, 18, 7
