Question

Петров положил в банк 10000 рублей под 4%годовых. сколько денег будет на его счете через год?

Answer 1

Ну от 100р- это 4 рубля, а от 10 000- это 400р в год. 
10 000+400=10 400р в конце года

Answer 2

Через год ему начислят 4%, то есть
10000•(4/100)=400 рублей

и на его счёте будет
10000+400=10400 рублей

Answer 3

To calculate the amount of money Petrov will have in his account after one year with a 4% annual interest rate, we can use the formula for simple interest:

Simple Interest = Principal (P) × Rate (R) × Time (T)

Where:

• Principal (P) is the initial amount of money deposited (10000 rubles, in this case).
• Rate (R) is the annual interest rate (4% or 0.04 as a decimal).
• Time (T) is the number of years (1 year, in this case).

Let's calculate it:

Simple Interest = 10000 rubles × 0.04 × 1 year Simple Interest = 400 rubles

Now, to find the total amount in Petrov's account after one year, we need to add the simple interest to the principal:

Total amount = Principal + Simple Interest Total amount = 10000 rubles + 400 rubles Total amount = 10400 rubles

So, after one year, there will be 10,400 rubles in Petrov's bank account.
