does
She get monthly.​

Answer 1

Lets suppose the income of Alka per month is P Rupees.

Now Alka spends 90% of the money every month.

We know that,

Saving = Income - Spended money

=> $120 = P - (P × \frac{90}{10})$

=> $120 = P - \frac{9p}{19}$

=> $120 = \frac{p}{10}$

=> $P = 1200$

This means that Alka earns 1200 Rupees per month.

Hope my answer Helped.
