• A. $18000$
• B. $20000$
• C. $22000$
• D. None of these
  

Answer 1

The correct option is C $22000$

Monthly Income = Saving + Expenditure

Let Monthly income be $x$

$x=\frac{12}{100}x+19360\Rightarrow x-\frac{12}{100}=19360\Rightarrow \frac{88}{100}x=19360\Rightarrow x=\frac{19360\ast 100}{88}=Rs.22000$
