Question

300000 руб разделены на две части из которых одна в 1,5 раза больше другой. меньшая часть положена в банк под 6% годовых. на большую часть приобретенные ценные бумаги, приносящие 3% годовых. сколько процентных денег получится с обеих частей по прошествии года?

Answer 1

1 + 1.5 = 2.5 частей
300 000 \ 2.5 = 120 000 - меньшая часть
300 000 - 120 000 = 180 000 - большая часть
120 000 * 0.06 = 7200 рублей составят проценты на 120 000
180 000 * 0.03 = 5400 рублей составят проценты на 180 000 рублей
7200 + 5400 = 12 600 рублей составят процентные деньги за год

Answer 2

300000/1,5 = 200000 большая часть под 3%
300000-200000 = 100000 меньшая часть под 6%
200000 * 3% = 200000/100*3 = 6000
100000 * 6% = 100000/100*6 = 6000
Итого 6000+6000 = 12000 руб.

Answer 3

Problem Analysis

We are given that 300,000 rubles are divided into two parts, with one part being 1.5 times larger than the other. The smaller part is deposited in a bank at an annual interest rate of 6%, while the larger part is used to purchase securities that yield an annual interest rate of 3%. We need to calculate the total amount of interest earned from both parts after one year.

Solution

Let's denote the smaller part as 'x' and the larger part as '1.5x'. We can set up the following equation to represent the total amount of money:

x + 1.5x = 300,000

Simplifying the equation, we have:

2.5x = 300,000

Solving for 'x', we find:

x = 300,000 / 2.5 = 120,000

Therefore, the smaller part is 120,000 rubles and the larger part is 1.5 times that, which is 180,000 rubles.

Now, let's calculate the interest earned from each part.

For the smaller part, which is deposited in the bank at an interest rate of 6%, the interest earned after one year is:

Interest = Principal * Rate = 120,000 * 6% = 7,200 rubles

For the larger part, which is invested in securities yielding an interest rate of 3%, the interest earned after one year is:

Interest = Principal * Rate = 180,000 * 3% = 5,400 rubles

Finally, to find the total amount of interest earned from both parts, we add the interest earned from each part:

Total Interest = 7,200 + 5,400 = 12,600 rubles

Therefore, the total amount of interest earned from both parts after one year is 12,600 rubles.

Answer: The total amount of interest earned from both parts after one year is 12,600 rubles.
