Question

The monthly salary for a person who follows the same expense pattern, but has a petrol expense of Rs 500 p.m., is:

Answer 1

Since the chart already gives each activity's share as a fraction of the full 360° circle, converting to a percentage is a single division.

School takes up $105°$ out of $360°$ total.
As a fraction, this is $\frac{105}{360} = \frac{7}{24} \approx 0.2917$.
As a percentage, this is about $29.2\%$, which rounds to the closest option, $30\%$.

So the correct answer is option B, 30%.
