Question 31
On a certain day when interviews for Master Degree courses were going on, it was found that 35 students attended interviews for MA Education, 47 students attended interviews for MSW and among the 2 groups, 12 students attended both. What is the total number of students who attended either of the interviews?
Solution
Let a = students who attended only MA
b= students who attended only MSW
c= students who attended both
a+c= 35
b+c = 47
c= 12
=> a=23 and b= 35
Total = a+b+c = 23 + 35 + 12 = 70
