    The "mode" is the most commonly-occurring number in a data set (if there is one). For example, for the set: 2, 3, 3, 5, 5, 5, 7, 8 the mode would be 5. I'm not sure what your numbers are: do you have 15 people under (age) 10? To answer this, we need to know what the numbers in the data set are...

    but my question is for finding mode by the formula we consider 109 to be the maximum frequency?

    The label "year under" seems to indicate a cumulative frequency table. Converting to a frequency table we get: Age group 0 ~ 9 10 ~ 19 20 ~ 29 30 ~ 39 40 ~ 49 50 ~ 59 No. persons 15 17 19 27 19 12 The largest group is in the 30 ~ 39 age range. The average age in this group can be estimated to be given by (30 + 39)/2 = 34.5 years old. Therefore the estimated mode is 34.5 years of age.
