Show answer & explanation

Correct answer: D

Explanation

 The correct answer is option 4 i.e.52

Understanding/Application

Let, Cost price of article = Rs 100

MRP = 100% above than CP [Given]

So, MRP = CP + 100% of CP = 100 + (100/100)100 = 100 + 100 = Rs 200

Now,

Two succsesssive discount on MRP = 5% + 20% 

So, net discount = 5 + 20 - (5 × 20)/100 = 25 - 1 = 24%

Therefore, SP = MRP - 24% of MRP = 200 - 24% of 200 = 200 - (200/100)24 = 200 - 48 = Rs 152

So, profit amount = SP - CP = Rs(152 - 100) = Rs 52

Profit% = (profit amount/CP)100 = (52/100)100 = 52%

Hence, x% = 52%

or x = 52
