Question: The average weight of 8 people increases by 2.5 kg if a new person replaces one weighing 50 kg. What is the weight of the new person

Answer: 

70 kg

Additional Information :

Given:

• The average weight of 8 people increases by 2.5 kg when a new person replaces one who weighs 50 kg.
• We need to find the weight of the new person.

Step 1: Calculate the Total Increase in Weight

Since the average weight increases by 2.5 kg for 8 people, the total weight increase is:

$$\text{Total increase} = 8 \times 2.5 = 20 \text{ kg}$$

Step 2: Find the Weight of the New Person

Let the weight of the new person be X kg.

Since the total weight increases by 20 kg, we can set up the equation:

$$X - 50 = 20$$ $$X = 50 + 20$$ $$X = 70$$

Final Answer:

The weight of the new person is 70 kg.
