A) \[52.6\]
B) \[52\frac{2}{3}\]
C) \[52\frac{1}{3}\]
D) None of these
Correct Answer: B
Solution :
Total weight of 45 students \[=45\times 52=2340\text{ }kg\] Total weight of 5 students who leave \[=5\times 48=240\text{ }kg\] Total weight of 5 students who join \[=5\times 54=270\text{ }kg\] Therefore, new total weight of 45 students \[=2340-240+270=2370\] \[\Rightarrow \]New average weight \[=\frac{2370}{45}=52\frac{2}{3}kg\]You need to login to perform this action.
