Question

a class has 26 boys and 3 girls the mean weight of boys of the class is 40 kg and mean weight of the girls of the class is 35 kg find the mean weight of the students of the class​

Answer 1

Answer:

mean weight of boys = 40 kg= total weight of boys / total number of boys

total weight of boys = 40× 26= 1040

mean weight of girls = total weight of girls/ total number of girls = 35

total weight of girls = 35× 3= 105

Therefore;

Mean weight of the students of the class = (1040+ 105)/29

=> 39.5 kg
