sol:

280=(70/100)x
x=(280*100)/70 =4*100=400.

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

(A) $348

(B) $364

(C) $392

(D) $400

(E) $420

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
