Answer 2

Answer:

19

Step-by-step explanation:

average of 35 student = 16 years

so sum of age of all student = 35 * 16 = 560

average of 21 students = 14 years

sum of age of 21 students = 21 * 14 = 294

average of remaining student = x

sum of ages of remaining 14 students = 14*x = 14x

sum of ages of all student = sum of age of 21 students + sum of age of 14 students

560 = 294 + 14x

14x = 216

x = 19
