Brief analysis of Shouyanxiang].

Solution: Let the pear have x boxes, the apple will lift and be 2x boxes, and Lie Fangsen's answer plan has 2x+x=621 x=207 2x=414

If you set x boxes of pears, then 160 x boxes of apples.

1－10％)x=160－x+30

90％x+x=190

190/100x=190

x=100160－x=60

A: It turned out that there were 60 boxes of apples and 100 boxes of pears.

Solution: Suppose there are x boxes of pears, then apples have (160-x) boxes

（1-10%）x=160-x+30

x=100Apples turned out to be: 160-100 = 60 (box).

Set the original pear x box, then.

x(1-10%)=160-x+30
