A seller makes a profit of 20% even after giving a discount of 10%. If the amount of profit on a TV set is ₹ 750, then the marked price of the TV set is:

Let Cost Price = $CP$

Given profit = 20%

So, profit amount = ₹750

$20%$ of $CP = 750$

$CP=\frac{750 \times 100}{20}$

$=3750$

Selling Price = $CP + Profit$

$=3750 + 750$

$=4500$

Discount = 10%

So, Selling Price = $90%$ of Marked Price

$90%$ of MP = 4500

$MP=\frac{4500 \times 100}{90}$

$=5000$

$\therefore$ Correct Answer: ₹5000 ✅
