    Answer: (b) 25 

    Solution:-
    According to the question look at the below diagram- 

    RE: Out of 100 students in a class, 60 take tea, 40 take coffee and 25 take both


    Then, the number of students who bot taking either tea or coffee = 100 – (35 + 25 + 15)
     = 100 – 75
     = 25

    Hence, the correct answer is option (b) 25.
