Let the marked price be M.
discount = 20%
Price = 1600

M= \frac{Price}{100-discount}  \times 100= \frac{1600}{100-20}  \times 100= \frac{1600}{80} \times 100=Rs.\ 2000

The marked price is Rs. 2000

Say the marked price was M_p
He was given off 20%, so 80% was what he paid. So:

\frac{4}5M_p=1600 \\\\ M_p=5\times\frac{1600}4 \\\\ M_p=\frac{5\times1600}4\\\\ \therefore M_p=400\times5\\=2000

Ans: $2000
