The following table shows the number of students of seven colleges participating in extra-curricular activities. Study the table and answer the question that follows.

The colleges in which the minimum number of students participate in extra-curricular activities are:

D and G

Number of students participate in extra-curricular activities from college A

= 150 + 50 + 100 + 250

= 550

Number of students participate in extra-curricular activities from college B

= 250 + 150 + 50 + 125

= 575

Number of students participate in extra-curricular activities from college C = 450 + 150 + 400 + 350 

= 1350

Number of students participate in extra-curricular activities from college D

= 50 + 50 + 125 + 275

= 500

Number of students participate in extra-curricular activities from college E 

= 350 + 50 + 100 + 250

= 750

Number of students participate in extra-curricular activities from college F 

= 250 + 50 + 500 + 150

= 950

Number of students participate in extra-curricular activities from college G 

= 150 + 50 + 150 + 100

= 450

So , Minimum number of students participate in extra - curricular activities are in D & G .
