Show answer & explanation

Correct answer: C

Explanation

 The correct answer is option 3 i.e. 12.5%

Understanding/Application

Let, MRP = Rs 100

Cost price = 80% of MRP = (100/100)80 = Rs 80

Now, gives 10% discount on sell. [Given]

Selling price = MRP - 10% of MRP = 100 - (100/100)10 = 100 - 10 = Rs 90

Profit amount = SP - CP = Rs(90 - 80) = Rs 10

Hence, profit% = (Profit amount/Cost price)100 = (10/80)100 = 1000/80 = 12.5%
