Answer 1

Answer:

(C) 36 years

Step by step Explanation :

Avg age of 25 students = 10

therefore, sum of ages of all students = 25 × 10 = 250

Avg age of 25 students and teacher = 10 + 1 = 11 years

therefore, sum of ages of all students and teacher = 26 × 11 = 286

therefore, age of teacher = 286 - 250 = 36 years
