" Total number of students after 16 years will be " color(brown)(14,970

Explanation:

Increase in number of students enrolled is compounded by 20% every year.

Hence it follows compound interest formula of

A = P(1 + (r/100)^n)

Total number of students after 16 years will be given by

a_16 = a_i * (1 + (r/100))^16

a_16 = 800 * (1.2)^16 ~~ 14,970 " students"
