Answer: B) Rs. 420

Given
Original Marked Price = Rs. 400
Let CP be X.
Now,
=> X + 33.33% of X = 400
=> 100X + 33.33X = 400 *100
=>X = 40000 /133.33 = Rs. 300 (Aprox.)
Let initial Profit be y, So
SP = 300 + y
New Profit = 2y and
New SP = (300 +y) + 16.66% of (300 +y) = (300 +y)*7/6
Now,
350 + 7y/6 -300 = 2y
5y/6 = 50
y = 60
Original Profit = Rs. 60
New Profit = 2y = Rs. 120
So, Increased SP = 300 + 120 = Rs. 420
