Marked priced of A is 1600 Rs more than its cost price. When discount on A is 500 there is a profit of 25% obtained. At what price A should be sold to obtain 30% profit.

MP = 1600 + CP ….(i)

MP – 500 = $frac{{125}}{{100}} imes CP$

4MP = 5CP + 2000 …(ii)

CP = 4400

Required selling price = $frac{{130}}{{100}} imes 4400 = 5720$
