A shop, which sold same marked price shirts, announced an offer - if one buys three shirts then the fourth shirt is sold at a discounted price of ₹100 only. Patel took the offer. He left the shop with 20 shirts after paying ₹20,000. What is the marked price of a shirt?

- ₹1260
- ₹1300
- ₹1350
- ₹1400
- ₹1500

**Answer**

Let marked price of 1 shirt be P.

Price of 4 shirts = 3P+100

It is given that 20 shirts cost Rs.20,000.

So, 4 shirts cost Rs.4,000.

3P + 100 = 4000

3P = 3900

P = 1300

**The correct option is B.**
