Question
The average weight of 8 persons increases by 3.5 kg when a new person comes in place of one of them weighing 72 kg. What might be the weight of the new person ?*1 point70 kg75 kg100 kg85 kg
Solution
To solve this problem, we need to understand that the average weight increases by 3.5 kg for 8 people. This means the total weight increased by 3.5 kg * 8 = 28 kg.
The new person replaced someone who weighed 72 kg. So, the new person must weigh 72 kg + 28 kg = 100 kg.
So, the weight of the new person might be 100 kg.
