Answer 2

Hey,
Thanks for asking this question.

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 × 90/100)
=> 120 = P - 9P/10
=> 120 = P/10
=> P = 1200

This means that Alka earns 1200 Rupees per month.


Hope my answer Helped.
