The average weight of the students in the college is 54 kg.
Given: There are 197 boys and 591 girls in a college. The average weight of boys is 63 kg and the average weight of girls is 51 kg.
To Find: The average weight of the students in the college.
Solution:
We know that the relation between the average weight and total weight of all the students can be given by the relation,
Average weight = Total weight of all students/Number of students ..(1)
Coming to the numerical, we are given;
Total number of boys = 197
The average weight of boys = 63 kg
The total weight of boys = ( 197 × 63 ) kg
= 12411 kg
Total number of girls = 591
The average weight of girls = 51 kg
The total weight of girls = ( 591 × 51 ) kg
= 30141 kg
So, the total weight of students = ( 12411 + 30141 ) kg
= 42552 kg
The total number of students = 197 + 591
= 788
So, we can find the average weight of students by putting the respective values in (1),
Average weight of students = 42552 / 788
= 54 kg
Hence, the average weight of the students in the college is 54 kg.
