Given: ​

Formula Used: ​

$$\frac{\text{Marked Price}}{\text{Selling Price}}= \frac{100+Profit}{100 - Discount}$$ 

Solution: ​

As per the qeustion;

$$\frac{\text{Marked Price}}{\text{Selling Price}}= \frac{100+20}{100 - 20}$$ 

​$$\frac{\text{Marked Price}}{\text{2000}}= \frac{120}{80}$$ 

Marked Price = $$\frac{ 120 \times 2000}{80} = ₹3000$$
