Question

The table shows the percentage distribution of students in four departments: 

Department	Percentage of Students
Physics	25%
Chemistry	30%
Mathematics	20%
Biology	25%

If there are 400 students in total, and 40% of Physics students are female, how many female students are in the Physics department?

• A. 40
• B. 50
• C. 60
• D. 80

Hint:

Calculate percentages step-by-step from total to specific category in data interpretation.

Answer 1

The Correct Option is A

We need to find female students in Physics.
- Step 1: Total Physics students: 400 students, Physics = 25% = \( 0.25 \times 400 = 100 \).
- Step 2: Female students: 40% of 100 = \( 0.4 \times 100 = 40 \).
- Step 3: Check options:
- (a) 40: Correct.
- (b) 50: Incorrect.
- (c) 60: Incorrect.
- (d) 80: Incorrect.
Thus, the answer is a.
