The average weight of 30 students is 60 kg. If one student is removed, the average drops to 59.5 kg. What is the weight of the removed student?
74.5 kg
Step 1 – Total weight of 30 students:
\(30 \times 60 = 1800 \text{ kg}\)
Step 2 – Total weight of remaining 29 students:
\(29 \times 59.5 = 1725.5 \text{ kg}\)
