Question

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

Answer 1

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 = ${\displaystyle \frac{\text{Increase}}{\text{Initial weight}}\times 100\%}$

= ${\displaystyle \frac{6}{60}\times 100\%}$

= ${\displaystyle \frac{60}{6}\%}$

= 10%

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