Answer 2

Answer:

the mean weight of students who left the class=58kg

Step-by-step explanation:

let total weight of 10 students is =x

then x÷10=50

x=500kg

let total weight of 8 students is y

then y/8=48

y=384 kg

total weight of those 2 students who left the class is =x-y=500-384=116kg

the mean weight of students who left the class = 116/2=58kg
