Question 2

Ekta earns Rs 1500 in 10 days. How much will she earn in 30 days?

Earnings of 10 days = Rs 1500

Applying unitary method, where firstly we find the value of one unit and then the value of required number of units.

$\therefore$ Earning of 1 day = $\frac{1500}{10}$ = Rs 150

$\therefore$ Earning of 30 days = 150 $\times$30 = Rs 4500

Thus, the earning of 30 days is Rs 4,500.
