Solution

The correct option is A 100
Number of students = 400

Out of every 20 students, 5 students are in Math club.

Therefore, the sample proportion = $\frac{5}{20}$

Estimated number of students in Math club = $\frac{5}{20}$ $\times$ 400

= 100

Hence, the estimated number of students in the Math club = 100
