Mathematics multiple-choice questions in the third grade of primary school
1: Because there are more orchids than Chinese rose 12, we know that the number of orchids is three times that of Chinese rose.

Therefore, the extra 12 flower is twice as much as the rose.

Then the rose has 12/2=6 orchids and 6*3= 18 orchids.

2. The tonnage of grain stored in warehouse A is three times that of warehouse B. If 260 tons are taken out of warehouse A and 60 tons are taken out of warehouse B, then the tonnage of grain stored in two granaries A and B is equal.

If each bin is put back to 60

That is, 260-60=200 is twice that of warehouse B.

So warehouse B has 200/2= 100 tons.

A warehouse has 100*3=300 tons.

3. If 2, Xiaogang has (8500-500)/2=4000 yuan.

Xiao Ming has 4000*3= 12000 yuan.

4. Same as the first question.

B There are 600/3=200 yuan.

A has 200*4=800 yuan.

5; Start with the first question.

There are 32/4=8 gray rabbits.

There are 8*5=40 white rabbits.

6. The tonnage of grain stored in warehouse A is three times that of warehouse B. If 80 tons are taken from warehouse A and brought into warehouse B, the tonnage of grain stored in warehouse A and warehouse B is exactly the same.

That is, A is 80+80 more than B =160 tons.

According to the first question

B has 160/2=80 tons.

A There are 80*3=240 tons.
