1. Suppose this clothing store bought X pieces of this kind of clothing for the first time.

2220/(960/x+5)=2x

2220= 1920+ 10x

x=30

This clothing store bought 30 such clothes for the first time.

Buying price =960/30=32 yuan.

So the total profit

=30(46-32)+60(46-32-5)

=420+540

=960 yuan

2. The three schemes are not clearly written and cannot be calculated.

1.26

Suppose X pieces are purchased for the first time, and the first purchase price is 960/x.

I bought 2X for the second time, and the purchase price was 2220/2X.

The price has the following relationship:

2220/2X-960/X=5

That is 150/X=5.

X=30

The first profit is 30*46-960= 1380-960=420.

The second quantity is: 60 pieces, of which 40 pieces are sold in 46 yuan, and the price of 20 pieces is 0.9*46=40.5 yuan.

So the second profit is: 40*46+20*40.5-2220=430 yuan.

So * * * Profit: 420+430=950 yuan.
