**The average age of 35 students in a class is 16 years. The average age of 21 students is 14. What is the average age of the remaining 14 students?**

### Note

The average age of 35 students is 16

The average age of 21 students is 14

∴ Average age of remaining 14 students = {(35×16)−(21×14)}/14

= (5 × 8) - 21

= (40 - 21)

**= 19 years**
