**Concept: The question tests on the fundamentals of Set theory **

**Solution: **A NEW OG 2021 QUESTION

Its a question testing on your application skills in Overlapping sets(Concept-Set Theory).

Seniors taking Calculus (C)= 80% = 80 students

Seniors taking BOTH Calculus and Physics( C AND P) = 60% of 80 =48 students

=>Thus, seniors taking ONLY Calculus = 80 -48 =32

Seniors taking neither calculus nor physics= 10% = 10 students

We know Total = Only C + (C & P) + Only P +Neither

=> 100 = 32 + 48+ Only P + 10

=> 100 = 32+ 48 + Only P + 10

=> Only P = 100-90 = 10

The total number of seniors taking Physics

= Only P + (C & P)

=10 + 48 =58

**(OPTION D)**
