Answer:
let the total stocks is X
20%of stock (.2X)
sell price of this stocks is .2x multiplied by 1.1= .22x
remaining stocks is .8x
50% of .8x = 0.4X sell at 10% loss
sell price of this stocks = .4x multiplied by .9 = 0.36x
total sell price on both transaction = .22x +.36X = .58x
again remainder stocks =0.4x
overall profit 5% on X =1.05X
sell price of reaming = 1.05 x-.58x = 0.47X
profit % = 0.47X- 0.40x/.4x
=.07 X100/.4 =17.5 %
Answer he should sale reaming .4x stock at the profit rate of 17.5 %
