SSC CGL 2024 (Tier-I) Previous Year Paper (17-Sep-2024) (Shift 3)
The correct answer is

16

From the given Venn diagram:

The number of students who like to study all three subjects (Physics, Chemistry, and Biology) is represented by the intersection of all three circles. This value is 4.

The number of students who like to study Biology only is represented by the section of the Biology circle that does not intersect with the other two circles. This value is 20.

To find the difference between the number of students who like to study all three subjects and the number of students who like to study Biology only, we subtract the two values:

Difference= 20-4 = 16
Thus, the difference is 16.
