A. 50
B. 500
C. 1000
D. 2000
E. 5000

Answer: B

Let the original price of the shirt be “x” dollars.
First it has decreased by 20%.
So, New price would have been x-\frac{20}{100}x=0.8x
Now the price again has increased by 20%.

So, 0.8x+\frac{20}{100}0.8x=0.96x

It is given that,
Solving it we get,
x = 500.

Hence the answer is B.
