Creating the frequency table from the given data , we have

From the given table, we need to find the frequency of each class interval
Class Interval(ages ) Frequency
4-7 85
7-10 140- 85 = 55
10-13 243 - 140 = 103
13 - 16 300 - 243 = 57

Hence from the given table , we see that
The number of students in the age group of 10 - 13 is 103
Least number of children are in the age group of 7-10
