To find out how much Ekta will earn in 30 days, we can use the concept of proportionality. Since the amount she earns is directly proportional to the number of days she works, we can set up a proportion:
\[\frac{\text{Earnings in 10 days}}{\text{Number of days}} = \frac{\text{Earnings in 30 days}}{30}\]
Given that Ekta earns 3000 Rs. in 10 days, we can write this as:
\[\frac{3000}{10} = \frac{X}{30}\]
where \(X\) is the amount she will earn in 30 days. Solving for \(X\):
\[X = \frac{3000 \times 30}{10} = 9000\]
So, Ekta will earn 9000 Rs. in 30 days.
