Given:  

Discount = 20%  

Selling Price (after discount) = Rs. 70  

We need to find the Marked Price.

---

Step-by-step solution:

Let Marked Price = x

After 20% discount, the customer pays 80% of the marked price.

So,  

80% of x = 70

Convert to equation:  

(80/100) × x = 70  

⇒ (4/5) × x = 70

Multiply both sides by 5:  

4x = 350

Now divide both sides by 4:  

x = 350 ÷ 4 = 87.5

Marked Price = Rs. 87.50
