(C) Marked Price $(M.P.)$ = $Rs. 720$.First discount = $10 \%$.Price after the first discount = $720 - (10 \% 	ext{ of } 720) = 720 - 72 = Rs. 648$.Let the second discount rate be $x \%$.Selling Price $(S.P.)$ = $Rs. 550.80$.Price after second discount = $648 - (x \% 	ext{ of } 648) = 550.80$.$648 	imes (1 - \frac{x}{100}) = 550.80$.$1 - \frac{x}{100} = \frac{550.80}{648} = 0.85$.$\frac{x}{100} = 1 - 0.85 = 0.15$.$x = 15 \%$.Therefore,the second discount rate is $15 \%$.
