The correct option is B $50
We know,
Selling price = Original price – Discount
Let 100x be the original price.
The discount provided is 60% on the original price.
So, discount amount
=60%×100x
=60100×100x
=60x
Actual selling price of the bag = 20 dollars
Substituting the values, we get:
$20=100x–60x
⇒$20=40x
⇒x=$2040=$0.5
So, value of 100x = 100 × 0.5 = $50
Hence, the original price is 50 dollars.
