.

MP=CP*multiplying factor of marked down

MP= CP*(7/10) (Multiplying factor is (7/10) because the price has been marked down by 30% i.e (100-30)/100= 7/10 )

280=CP*(7/10)

CP=$400

IMO D is the answer

Let the original amount be Rs x
Now a discount of 30% has been given to achieve a rate of $280
Therefore the equation is
x(1-30/100)=280
Solving we get x=400
Thus option D is the answer

Since the band was marked down by 30%, its sale price of $280 is 70% of its original price n. We can create the equation:

0.7n = 280

n = 400
