1. There are more apples than Sydney 1 1 box. If you subtract 1 1 box from the total weight, the weight of the apple is1626-11*18 =1438. Then, the number of cases of apples is 34+ 1 1=45, and the number of cases of Sydney is 34.
2. The length is increased by 4 meters, and the area is increased by 240 square meters, indicating that the width is 240/4=60 meters; The width is increased by 3 meters, and the area is increased by 240 square meters, that is to say, the length is 240/3=80 meters, and the original area is 80 * 60 = 4,800 square meters.
3. The length of flagpole is 3.3 * 8.4/2.1=13.2m..
4. The upper layer takes out 30 books for the lower layer, and there are as many books in the two layers, which is equivalent to the upper layer taking out 60 books directly, and there are as many books in the upper and lower layers; It turns out that the number of upper-level books is more than three times that of lower-level books, 10, so the number of lower-level books is twice equal to 60- 10 = 50, so the lower-level books are 25 and the upper-level books are 25 * 3+ 10 = 85?
