Question

out of total salary Mrs Rohini Spends 20% on house rent and 60% of the rest for household expenditure,if she saves ₹2800,what is her total salary?​

Answer 1

Answer:

Let x be Tanvy monthly salary.

Here House rent =30% of x

=10030x

=103x

Household expenses =60% of x

=10060x

=106x

∴ Total saving=10500

⇒x−(103x+106x)=10500

⇒x−109x=10500

⇒10x=10500

⇒x=1,05,000

∴ Tanvy monthly salary =Rs. 105000.
