Пусть масса дыни - х кг, тогда арбуза - 2х кг, значит:
3х+2х=10
5х=10
х=10:5
х=2
2х=2*2=4
Ответ: масса арбуза 4 кг.

Never before in the history of the world have businessmen traveled as much as they do today. It is not surprising because we are living in a world of growing international trade and expanding economic and technical cooperation. Employees of different countries usually go on business trips for many reasons: to make a contract, to discuss different terms of delivery, payment or shipment, to have tests, to do consultancy, to improve once professional skills, to work etc. Business trips contribute to extension of business relationship of a company and help to succeed in the world market.
Companies can arrange such trips both in and outside the country. Usually itinerary of the trip is carefully planned by the head of the department or an executive. A business trip can be a long term or a short term one. Often an employee must give a financial report to the chief so he usually needs to save the receipts from restaurants, hotels, and taxi rides.
On a business trip people may meet colleagues and business partners for a first time. It is usual for colleagues from different countries to experience cultural difficulties. In some cases it is useful to get a piece of advice from a special agency, consulting on the questions of international business.
Being away from home means not having access to everything you’re accustomed to, so take careful preparations for your trip and write down everything you’ll need to bring, including clothes, toiletries, and anything from the office you’ll need for work.
Though it is fascinating for tourist travelling, it has become the most tiring of all occupations for many businessmen and experts. Therefore, choosing a comfortable hotel conveniently located to stay at is a matter of big importance.
When traveling for work, you become the face of your employer. It is important to make a good impression and good connections when you meet people for work.
