Every year before the festive season,a shopkeeper increases the price of the product by 35% and then introduce two successive discount of 10% and 15% respectively.what is percentage loss and percentage gain ?
Let C.P = 100
35% increase in S.P = Rs 135
10% discount in Rs 135 = 135×10100=13.5
sp 1st S.P = 135-13.5 = 121.5
Again 15% discount in 1st S.P = 121.5×15100
=18.225
2nd S.P = 121.5−18.225=103.275
So finally C.P = 100, S.P = 103.275
Gain by 103.275−100=3.20% = 3.275%
