Given:

Geeta saves = 20% of her monthly salary

Geeta's saving amount = ₹ 43,500

Let the salary of Geeta be $x$ . Hence,

20% of $x$ = 43,500

⇒ $\dfrac{20}{100} \times x = 43,500$

⇒ $\dfrac{1}{5} \times x = 43,500$

⇒ $x = \dfrac{43,500 \times 5}{1}$

⇒ $x = 2,17,500$

Geeta's expenditure = (100% - 20%) of her monthly salary

= 80% of her monthly salary

= $\dfrac{80}{100} \times 2,17,500$

= $\dfrac{4}{5} \times 2,17,500$

= $\dfrac{8,70,000}{5}$

= $1,74,000$

Hence, Geeta's monthly expenditure = ₹ 1,74,000.
