Mathematical pothole problem
1, original x for large bottle and 3-x for small bottle.

3x/4 : (x/4+3-x) = 3 :2

2. Set xKG water.

35: 100 =(2000 * 65%):(2000+X)

3. If the length is x, the width is (140-2x)/2.

x : ( 140-2x)/2 =4:3

4. Let the number of copies to be completed by each person be X (the number of copies of two people should be equal).

x/6 : (x-96)/6 = 5:4

5, containing liquid x g.

X: 8008 = 1: 100 1 because medicine: water = 1: 1000, medicine: medicinal liquid =1:100/kloc.

6. Suppose there is a ***x student in grade six, and then there are girls (x-3)/2 boys (x+3)/2.

(x+3)/2:(x-3)/2 = 13: 12
