$<b><i><font face=Copper black size=4 color=blue>$ Here is your answer.
Let the Marked price is 100
Discount % = 15%
so Discount = 15

CP = 100 - 15
= 85
As Radhika sold at Marked price
SP = 100

PROFIT = 100 - 85
= 15

PROFIT % = Profit × 100/CP
$= \frac{15 \times 100}{85} \\ = \frac{1500}{85} \\ = 17.64\%$

Therefore Radhika Gain% is = 17.64%
