Problem:
The average weight of 24 students in a class is 40 kg. If the weight of the teacher is included, the average is increased by 500 gms. Find the weight of the teacher.

Solution:
Let's assume the weight of the teacher is 'T' kg.

Step 1: Calculate the total weight of the students:
The average weight of 24 students is given as 40 kg. Therefore, the total weight of the students can be calculated as:
Total weight of students = Average weight * Number of students = 40 kg * 24 = 960 kg

Step 2: Calculate the new average with the teacher's weight:
When the weight of the teacher is included, the average increases by 500 gms or 0.5 kg. Therefore, the new average can be calculated as:
New average = Average weight + Increase in average = 40 kg + 0.5 kg = 40.5 kg

Step 3: Calculate the total weight with the teacher's weight:
The total weight with the teacher's weight can be calculated by multiplying the new average by the total number of people, which includes the students and the teacher:
Total weight with teacher = New average * (Number of students + 1) = 40.5 kg * (24 + 1) = 40.5 kg * 25 = 1012.5 kg

Step 4: Calculate the weight of the teacher:
To find the weight of the teacher, we subtract the total weight of the students from the total weight with the teacher's weight:
Weight of the teacher = Total weight with teacher - Total weight of students = 1012.5 kg - 960 kg = 52.5 kg

Therefore, the weight of the teacher is 52.5 kg, which corresponds to option 'B'.
