Question 61

The average weight of 6 people increased by 2.5 kg when a new person came in place of other person weighing 55 kg. what can be the weight of new person (in kg)?

Solution

Total weight increased = number of persons $$\times\ $$ increased weight

i.e;$$6\times\ 2.5=15$$

Weight of new person = weight of replaced person + Total increased weight

i.e; 55 + 15 = 70 kg

Hence, Option A is correct.
