Dịch : Alex có 1 bộ sưu tập huy hiệu rất tuyệt mà anh ấy muốn đếm.Anh ấy biết rằng số huy hiệu nằm trong khoảng 120 -> 150 nhưng ko biết chính xác con số.Anh ấy quyết định đếm nhóm 5 và dư ra 2.Sau đó anh ấy đếm nhóm 6 và dư ra 3.Bạn có thể tính chính xác số huy hiệu mà Alex có ko ?

Giải : Gọi số huy hiệu Alex có là a\(\left(120\le a\le150\right)\)thì a : 5 dư 2 ; a : 6 dư 3

=> a + 3 chia hết cho 5 và 6 (vì 5 - 2 = 3 ; 6 - 3 = 3) => (a + 3)\(⋮\)30 => a + 3 = 150 (vì\(123\le a\le153\)) => a = 147

Vậy Alex có 147 huy hiệu

Chỗ\(123\le a\le153\) sửa a thành a + 3 nhé.

Vấn đề 8. Một container có hình khối có kích thước như trong hình. Các thùng có 54 lít nước trong đó. Bình muốn biết một xô đầy chứa bao nhiêu lít nước , do đó, ông đổ cả xô nước vào container và thấy rằng mức độ của nước tại 7 8 là chiều cao của container. Từ đó, ông có thể tính toán bao nhiêu lít nước một xô đầy chứa . Nếu container rỗng , bao nhiêu xô nước phải Bình đổ vào các container để làm cho nó đầy đủ?

To solve this problem, let's break it down step by step.

Step 1: Calculate the volume of the cuboid container.
The volume of a cuboid is given by the formula:
Volume = Length × Width × Height

Given:
Length = 12 meters
Width = 6 meters
Height = 4 meters

Volume = 12 × 6 × 4 = 288 cubic meters

Step 2: Convert the volume to liters.
Since 1 cubic meter = 1000 liters, we have:
Volume = 288 × 1000 = 288,000 liters

Step 3: Determine the volume of water after pouring a full bucket.
The water level after pouring the bucket is at 7/8 the height of the container, which means the volume of water is 7/8 of the volume of the container.

Volume of water = (7/8) × 288,000 liters = 252,000 liters

Step 4: Calculate the volume of water in one bucket.
Since initially, there were 54 liters in the container and after pouring the bucket, there were 252,000 liters, the volume of water in one bucket can be found by subtracting the initial volume from the final volume.

Volume of water in one bucket = 252,000 liters - 54 liters = 251,946 liters

Step 5: Determine how many buckets are needed to fill the container.
To find out how many buckets are needed to fill the container, divide the volume of the container by the volume of water in one bucket.

Number of buckets needed = 288,000 liters / 251,946 liters ≈ 1.144

Since Bình cannot pour a fraction of a bucket, he would need to pour 2 buckets of water to fill the container completely.

KING MIDAS AND THE GOLDEN TOUCH

Long ago , in Ancient Greece , there wasa king named Midas .He lived in an enormous palace with his wife and his daughter . King Midas was very , very rich . He had more gold than any other king in the world . Hí palace was full of gold statues , gold jewellery and gold coins , but Midas was greedy and he always wanted more .

One day , the king was walking in the garden of his palacewith his daughter .She was picking yellow flowers for her room . "Those yellow flowers are very beautiful ," King Midas said , "but gold flowers aer more beautiful."

The king's daughter ran back into the palace with her flowers and the king walked alone . Then Midas made a wish . He wished that everything he touched became gold . Soon he touched a flower . It became gold . He touched a tree and it became gold .He touched a plant and it too was gold . "My wish has come true !" he shouted .

The king touched many things in his garden and in his palace . He touched pictures and vases and plates and they all became gold .Soon Midas was hungry and thirsty . But , When he put some bread in his moth ,it turned to gold. And when he put some water to his lips , it also turned to gold .

The king sat in his garden ."I have all the gold in the world ," he thought,"but i cannot eat and i cannot drink.What shalli do ?"

At last , the king's daughter saw her father in the garden . She ran to him because he looked so sad .She touched his hand and suddenly she became gold , too. King Midas made another wish . He wished that he could have his daughter back and he wished  to not have any more gold . Suddenly , all the gold was gone and his daughter was playing happily in the garden . King Midas had learnt his lesson and he never asked for more gold again.
