The average age of 34 boys in a class is 14.If teachers age is include...
Given:
Number of boys in the class = 34
Average age of the boys = 14
To find:
Teacher's age
Approach:
1. We can start by finding the sum of the ages of the boys using the formula: Sum = Average × Number of boys.
2. Then, we can find the total age of all the people in the class (including the teacher) using the formula: Total age = New average × Total number of people.
3. Finally, we can find the teacher's age by subtracting the sum of the ages of the boys from the total age of all the people in the class.
Calculation:
1. Sum of the ages of the boys = 14 × 34 = 476.
2. Let's assume the teacher's age is T.
Total age of all the people in the class = New average × Total number of people
= 15 × (34 + 1) [Adding 1 for the teacher]
= 15 × 35
= 525.
3. Teacher's age = Total age - Sum of ages of the boys
= 525 - 476
= 49.
Conclusion:
The teacher's age is 49 years old.
Number of boys in the class = 34
Average age of the boys = 14
