Ok let us do it
Consider X is the price of first dress
cost of second dress is (1648 - X)
Selling price of first dress = X x 115/100 (selling price = cost of dress 100% + profit 15%)
Selling price of second dress = (1640 - X) x 91/100 (selling price = cost of dress 100% - loss 9%)
Selling price of 1st dress = Selling price of second dress
X x 115/100 = (1640 - X) x 91/100
115X/100 = 1640 x 91 - 91X/100
115X + 91X = 1640 x 91
206X = 1640 x 91
X = 1640 x91/206
X = 724.4660
Cost of first fress = Rs. 724.47
Cost of second dress = 1640 - 724.47 = Rs 915.53
