  1. CORRECT ANS IS
    Adding the number of students taking French
    and the number of students taking chemistry and
    then subtracting the number of students taking both
    yields (63 + 48) – 21 = 90. This is the number of
    students enrolled in either French or chemistry or
    both. Since the total school enrollment is 150,
    there are 150 – 90 = 60 students enrolled in neither
    French nor chemistry. The answer is (A).
