Ram, Shyam, Rohan, Reeta and Mukesh are five members of a family who are weighed consecutively and their average weight is calculated after each member is weighed. If the average weight increase by 2 kg each time, how many heavier is Mukesh than Ram?
Answer & explanation
Correct answer: option 3
Let's assume weight of Ram is x kg.
Avg. weight of first four members = x+6
Avg. weight of first four members = x+8
So, weight of fifth member= 5(x+8) - 4 (x+6)= x+16
Mukesh id 16 Kg heavier than Ram
