43-39=4 г, разница между детьми, (16-4)/2=6 лет младшей/ му (не важно), соответствено 10лет старшему/ей, 43-10=33 года маме или 39-6=33 года.

Мать - xСын - yДочь - zx+y=43x+z=39y+z=16y=16-z, z=39-x => y=16-(39-x)Подставляем в первое уравнение: x+16-(39-x)=43 x+16-39+x=432x=66x=33Матери 33 года.

Property law

A painting of the South Sea Bubble, one of the world's first ever speculations and crashes, led to strict regulation on share trading.

Property law governs valuable things that people call 'theirs'. Real property, sometimes called 'real estate' refers to ownership of land and things attached to it. Personal property, refers to everything else; movable objects, such as computers, cars, jewelry, and sandwiches, or intangible rights, such as stocks and shares. A right in rem is a right to a specific piece of property, contrasting to a right in personam which allows compensation for a loss, but not a particular thing back. Land law forms the basis for most kinds of property law, and is the most complex. It concerns mortgages, rental agreements, licences, covenants, easements and the statutory systems for land registration. Regulations on the use of personal property fall under intellectual property, company law, trusts and commercial law.

An example of a basic case of most property law is Armory v Delamirie. A chimney sweep's boy found a jewel encrusted with precious stones. He took it to a goldsmith to have it valued. The goldsmith's apprentice looked at it, sneakily removed the stones, told the boy it was worth three halfpence and that he would buy it. The boy said he would prefer the jewel back, so the apprentice gave it to him, but without the stones. The boy sued the goldsmith for his apprentice's attempt to cheat him. Lord Chief Justice Pratt ruled that even though the boy could not be said to own the jewel, he should be considered the rightful keeper ("finders keeper") until the original owner is found. In fact the apprentice and the boy both had a right of possession in the jewel (a technical concept, meaning evidence that something could belong to someone), but the boy's possessory interest was considered better, because it could be shown to be first in time. Possession may be nine tenths of the law, but not all.

This case is used to support the view of property in common law jurisdictions, that the person who can show the best claim to a piece of property, against any contesting party, is the owner. By contrast, the classic civil law approach to property, propounded by Friedrich Carl von Savigny, is that it is a right good against the world. Obligations, like contracts and torts are conceptualised as rights good between individuals. The idea of property raises many further philosophical and political issues. Locke argued that our "lives, liberties and estates" are our property because we own our bodies and mix our labour with our surroundings.
