The sum of the ages of 23 A, B and C is 113 years old, and they are the age of A.

1 Three households in Building No.1 have a one-time deposit of 2,7 yuan. The Li family saves less in 25 yuan than the Wang family, and the Wang family saves more in 8 yuan than the Zhang family. How much does each of them save?

A cage can hold 18 rabbits and 9 chickens of the same size, or 14 rabbits and 15 chickens of the same size. If it is specially used for rabbit cages, how many rabbits can it hold at most?

3 A, B and C, A is 3 years older than B, B is 2 years younger than C, and the sum of their ages is 19. How old are they?

4 The Young Pioneers' No.1, No.2, No.3 Squadron * * * killed 2 rats. The number of rats killed by the No.2 Squadron was twice as much as that of the No.1 Squadron. The number of rats killed by the No.3 Squadron was 4 more than the sum of the No.1, No.2 Squadron. How many rats were killed by each of the three squadrons?

division sign * is multiplication sign

1. Solution: Let's say that the Wangs have a deposit of X yuan, the Li family has a deposit of x-25, and the Zhang family has a deposit of x-8 yuan.

x+(x-25)+(x-8) = 27

3x-33 = 27

3x = 27+33

3x = 33

x = 11

x-25.

2. Solution: Let the cage be m, a rabbit occupy space X and a chicken occupy space y.

m=18x+9y

m=14x+15y

Available: 18x+9y = 14x+15y

4x = 6y

2x.

3. Solution: Let the age of B be X, the age of A be 2x+3, and the age of C be (x+2)/2.

X+2x+3+(x+2)/2 = 19

3x+1/2x+4 = 19

.

4. solution: the first squadron is set to kill x rats, the second squadron to kill 2x+5 rats, and the third squadron to kill 3x+9 rats.

note: x+2x+5+4=3x+9!

x+2x+5+3x+9 = 2

6x+14 = 2

6x = 186

x = 31

2x+5 = 67

3x+9 = 12

A: The first squadron killed rats.

6. Children in kindergarten are given candy, and each child is given 1 candies, but two of them are not given. If each child is given 8 candies, how many children are asked? How many sweets are there?

7. Students planted trees on Arbor Day, and each of them planted six trees, leaving four trees. If three of them planted five trees each and the rest planted seven trees each, how many students planted trees?

5. solution; Suppose that X tons need to be transported from warehouse B and put into warehouse A

3*(14-X)=18+X

X=78

A; Suppose that 78 tons need to be transported from warehouse B to warehouse A.

6. There should be 8 sweets and 1 children.

Solution: Let x children

1*(X-2)=8*X

X=1

So the number of sweets is 8 * 1 = 8

. Someone walks 2 kilometers per hour up the mountain and 5 kilometers per hour down the mountain. It takes him 38 hours to walk from Nanzhen to Beizhen and 32 hours to walk from Beizhen to Nanzhen. Q: How many kilometers is the distance between the two towns?

It takes 32+38=7 hours for this person to go back and forth.

The uphill and downhill distances are equal.

So it takes 7/(5+2)*5=5 hours to go uphill.

The distance between the two towns is 5*2=1 kilometers.
