उत्तर

Weight of Nikhil increased from 60 kg to 66 kg. Then, the increase in weight is 10 %.

Explanation:

We have, initial weight of Nikhil = 60 kg

After increase in weight, weight became = 66 kg

Increase in weight = 66 – 60 = 6 kg

∴ Increase percentage of weight

= `"Increase"/"Initial weight" xx 100%`

= `6/60 xx 100%`

= `60/6%`

= 10%

So, the number of students present on that day was 46.
