Answer 1

Answer:

Correct option is (D): 200

Step-by-step explanation:

Let say "x" is the total number of students.

Then, Number of students more than 20 years of age

= (100 - 63)% of x = 37% of x.

37% of x = 42 + 2/3 of 48

37/100 x = 74

x = 200

Thus the total number of students in the ABC College is 200.
