Answer:
160.5
Step-by-step explanation:
mean weight of 40 students of a class is 150 cms
total weight of 40 students is 40*150=6000
if 2 more students added total number of students are 40+2=42
mean weight of 42 students of a class is 150.5 cms
total weight of 40 students is 42*150.5=6321
Difference 6321-6000=321
means of 2 students is 321/2=160.5
