The correct option is C Rs135 Profit
Cost price of 1 T-shirt before discount = Rs 300
Cost price of 1 T-shirt after discount = Rs 300 - 300 x 10/100 = Rs 300 - 30 = Rs 270
Therefore cost price of 5 T-shirts = Rs 270 x 5 = Rs 1350.
According to question total selling price of 5 T-shirts = Rs 1485
Since Selling Price > Cost price so Sohan earns a profit.
Now Profit = Selling Price - Cost Price = Rs (1485 - 1350) = Rs 135
