A trader marked his goods at 20% above the cost price of Rs.245346. He sold half the stock at the marked price, one-quarter at a discount of 20% on the marked price and the rest at a discount of 40% on the marked price. His total gain is- (a) 2% (b) 15% (c) 2.75% (d) 13.5% (e) None of these

Hi, it doesnt depend upon the acutal value of C.P, If his C.P is 100, then M.P = 120,let us calculate his total amount received or S.P = (120*1/2 + 120*1/4*0.8 + 1/4*120*0.6) = 102His C.P is 100, so gain is 2%
