**The average weight of 8 person’s increases by 2.5 kg when a new person comes in place of one of them weighing 65 kg. What is the weight of the new person?**

- 75 Kg
- 50 Kg
- 85 Kg
- 80 Kg

**Answer: 3**

**Solution: **

Total increase in weight = 8×2.5=20

If x is the weight of the new person, total increase in weight = x – 65

=> 20 = x – 65

=> x = 20 + 65 = 85
