Given Marked Price or Labbeled Price = 720
After giving successive discounts the selling price = 550.80
Therefore , they have also given that one of the successive discount is 10% , to find the other :

SP = MP(1-(discount1/100))(1-(discount2/100))

from this we can keep discount2 as x and find it

550.85 = 720 (1-(10/100))(1-(x/100))
0.85 = 1-(x/100)
x = 0.15 * 100
discount2 = 15%

720*0.90*x=550.80
x=0.85
so second discount is 1-0.85=0.15 or 15%
