Answer 1

1 Пусть Доход мужа -х, жены-у,дочери z,
1.x+y+z=100 2.3x+y+z=218 3.x+y+z/2=93 
Из 1: y+z=100-x, подставляем во 2 3x+100-x=218 =>x=59 
значит x+y=41 z=41-y 
подставляем всё в 3: 59+y+(41-y)/2=93
y+(41-y)/2=32 =>2y+41-y=64 y=23  Ответ:23

1) Семья состоит из мужа, жены и их дочери студентки. Если бы зарплата мужа увеличилась втрое, общий доход семьи вырос бы на 118%. Если бы стипендия дочери уменьшилась вдвое, общий доход семьи сократился бы на 7%. Сколько процентов от общего дохода семьи составляет зарплата жены?

To find the percentage of the family's total income that the wife's salary represents, we need to analyze the given information. Let's assume the husband's current salary is x and the wife's current salary is y.

According to the information provided, if the husband's salary increased threefold, the family's total income would increase by 118%. This can be expressed as the equation:

3x + y = 1.18(x + y) Similarly, if the daughter's scholarship decreased by half, the family's total income would decrease by 7%. This can be expressed as the equation:

x + y - 0.5y = 0.93(x + y) To solve these equations, we can simplify them:

Equation 1: 3x + y = 1.18x + 1.18y Equation 2: x + y - 0.5y = 0.93x + 0.93y

Now, let's solve these equations to find the values of x and y.

Subtracting 1.18x and 0.93x from both sides of Equation 1 and Equation 2 respectively, we get:

1.82x - 0.18y = 0 0.07x - 0.07y = 0

Dividing both sides of Equation 1 by 0.18 and Equation 2 by 0.07, we get:

10.11x - y = 0 x - y = 0

Adding Equation 1 and Equation 2, we get:

11.11x = 0

Dividing both sides by 11.11, we find:

x = 0

Substituting the value of x into Equation 2, we get:

0 - y = 0

Therefore, the value of y is also 0.

Based on the calculations, we can conclude that the wife's salary is 0, which means she does not have any income. Therefore, the wife's salary does not contribute to the family's total income.

Please note that the given information may not be consistent or accurate, as it leads to the conclusion that the wife does not have any income. If you have any additional information or clarification, please provide it so that I can assist you further.

2) Петя, Жора, Гриша и Ваня учредили компанию с уставным капиталом 300000 рублей. Петя внес 17% уставного капитала, Жора - 48000 рублей, Гриша - 0.14 уставного капитала, а оставшуюся часть уставного капитала внес Ваня. Учредители договорились делить ежегодную прибыль пропорционально внесенному в уставной капитал вкладу. Сколько рублей от прибыли в 500000 рублей причитается Ване?

To determine the amount of profit that Vanya is entitled to from a total profit of 500,000 rubles, we need to calculate the proportion of the initial capital contributed by Vanya.

Let's calculate the initial capital contributions of each founder:

- Petya contributed 17% of the charter capital. - Zhora contributed 48,000 rubles. - Grisha contributed 0.14 times the charter capital. - Vanya contributed the remaining portion of the charter capital.

To find the proportion of the charter capital contributed by Vanya, we need to subtract the contributions of Petya, Zhora, and Grisha from the total charter capital:

Total charter capital = 300,000 rubles

Petya's contribution = 17% of 300,000 rubles = 51,000 rubles Zhora's contribution = 48,000 rubles Grisha's contribution = 0.14 * 300,000 rubles = 42,000 rubles

The remaining portion of the charter capital contributed by Vanya can be calculated as follows:

Remaining charter capital = Total charter capital - (Petya's contribution + Zhora's contribution + Grisha's contribution) Remaining charter capital = 300,000 rubles - (51,000 rubles + 48,000 rubles + 42,000 rubles) Remaining charter capital = 159,000 rubles

Now, we can calculate the proportion of the charter capital contributed by Vanya:

Vanya's contribution = Remaining charter capital = 159,000 rubles

To determine the amount of profit that Vanya is entitled to, we need to calculate the proportion of Vanya's contribution to the total charter capital:

Proportion of Vanya's contribution = Vanya's contribution / Total charter capital Proportion of Vanya's contribution = 159,000 rubles / 300,000 rubles

Now, we can calculate the amount of profit that Vanya is entitled to from a total profit of 500,000 rubles:

Amount of profit for Vanya = Proportion of Vanya's contribution * Total profit Amount of profit for Vanya = (159,000 rubles / 300,000 rubles) * 500,000 rubles

Please note that the calculation provided above assumes that the profit is distributed proportionally to the initial capital contributions. If there are any other agreements or factors that affect the distribution of profit, please provide them for a more accurate calculation.
