Answer» Cost price of 250 packets of blades CP = 2508 = Rs 2000 Selling price of blades SP= (70/100)25011 + (30/100)2509= 2577 + 759= 1925 + 675= 2600 Therefore,Gain % = [(SP - CP)/CP]×100= [(2600 - 2000)/2000]100= (600/20)= 30%

Answer»

Cost price of 250 packets of blades CP = 250*8 = Rs 2000

Selling price of blades SP= (70/100)*250*11 + (30/100)*250*9= 25*77 + 75*9= 1925 + 675= 2600

Therefore,Gain % = [(SP - CP)/CP]×100= [(2600 - 2000)/2000]*100= (600/20)= 30%
