Adults: 44-27= 17

Number of children: (27- 17)*2=20

Explanation: No matter adults or children, each pole has at least one bucket of water (children are two children carrying one bucket of water, adults are two buckets of water), then use 44 -27 buckets of water, that is, the extra water picked by these poles. Which part has more water? Adults carry more water, how much more each person has, and each person has an extra bucket, so

(44-27)/ 1=44-27= 17

It is easy to count the number of children. How many people do you need for the remaining 10 shot? Children are two children carrying a bucket of water, so it is (27- 17)*2=20.
