Respuesta :
Total students = Students who studied Economics + Students who studied Geography - Students who studied both subjects
Given:
Students who studied Economics (E) = 65
Students who studied Geography (G) = 50
Total students = 80
We need to find the number of students who studied both subjects.
Using the formula:
Total students = E + G - Both
Plugging in the values:
80 = 65 + 50 - Both
Now, solve for Both:
Both = 65 + 50 - 80
= 115 - 80
= 35
So, 35 students studied both Economics and Geography.
