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?

  1. 75 Kg
  2. 50 Kg
  3. 85 Kg
  4. 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
