Let the Cost Price be ₹100.Then,the price that has been set is ₹130 (₹30 above C.P).Now,a discount of 15% has been given on this new selling price.Discount given = ₹ (15/100 * 130) = ₹ 19.5
So the ultimate selling price is ₹(130 - 19.5) = ₹ 110.5
Gain % = {(S.P - C.P/C.P) * 100}% = {(10.5/100) * 100}% = 10.5%
