Question

в магазине продаются мужские и женские рубашки. В понедельник купили несколько рубашек, а несколько рубашек проданных ранее - вернули в магазин. После этого , общее количество рубашек уменьшилось на 5% , а процент оставшихся женских рубашек увеличился с 40% до 45% . Вопрос: увеличилось или уменьшилось количество женских рубашек?

Answer 1

На начало понедельника в магазине было 20х рубашек - 8х женских (20X * 40% /100%) и 12х мужских. После окончания понедельника общее число

рубашек уменьшилось на 5% - теперь их было 19X

(20X * 95% /100%). Женских рубашек теперь не 40%, а

45%, то есть 19X *45%/ 100% = 8.55 X.

Было их 8х, а стало 8.55Х. Очевидно, их число увеличилось.

Answer 3

Understanding the Question

The question is asking whether the number of women's shirts increased or decreased after some shirts were bought and returned to the store. The information given is that the total number of shirts decreased by 5%, and the percentage of remaining women's shirts increased from 40% to 45%.

Analyzing the Information

To determine whether the number of women's shirts increased or decreased, we need to consider the percentage change in the total number of shirts and the percentage change in the number of women's shirts.

Calculating the Percentage Change

Let's assume there were initially 100 shirts in total. If the total number of shirts decreased by 5%, there would be 95 shirts remaining.

If the percentage of women's shirts increased from 40% to 45%, we can calculate the number of women's shirts before and after the change:

- Initially, there were 40 women's shirts (40% of 100). - After the change, there would be 42.75 women's shirts (45% of 95).

Answer

Based on the calculations, the number of women's shirts increased from 40 to 42.75. Therefore, the number of women's shirts increased.

Note: The calculations above are based on the assumption that there were initially 100 shirts in total. The actual number of shirts is not provided in the question, so we had to make an assumption for the calculation.
