Many put money in bank to secure themselves against inflation. The major criterion when choosing bank is the interest rate, that is some percentage share from the initial capital which to it is added by bank that you keep this money in this bank. Sometimes it is necessary to count income from this financial transaction for several years. And the method of difficult percent will help with it.
Instruction
1. For a start we will understand as percent in the first year are charged. The increase for example for 10% per annum goes on the following formula: É = X + 0.1*X =1.1*HTakim in the way, P will be in 1.1 times more, than X - the initial sum.
2. Further for charges in the next years it is necessary to use the same formula, only instead of X we will use River. Thus the formula will take a form: M = P+0.1*P=1.1*P=1.21*X. As a result in two years we increased the initial capital already by 1.21 times.
3. Speaking to mathematical language, we deal with indicative which grows as speak, after the exhibitor. In simple terms, each subsequent percent to you charge about all of the increasing sum and in 7 years at you on the account will be in 2! time there are more money, than you put.
4. Difficult percent are one of the major concepts of banking therefore if you sometime deal with bank deposits and a mortgage, it is better to know calculation of these percent by heart.
