Solution

The correct option is C $$40$$
The number of students preferring Psychology $$=\dfrac{216}{360}\times 100 = 60$$

The number of students who prefer Social Science $$=\dfrac{72}{360}\times 100 = 20$$

The number of students who prefer Psychology is more than the students who prefer Social Science $$=60 - 20 = 40$$
