Weight of Nikhil increased from 60 kg to 66 kg. Then, the increase in weight is 10 %.
From the question it is given that, Weight of Nikhil increased from 60 kg to 66 kg.
So, weight increase = 66 – 60
= 6 kg
Then, percentage increase = (Weight increase/Initial weight) × 100%
= (6/60) × 100
= 600/60
= 60/6
= 10%
