Question

Машинистка должна была напечатать за определенное время 200 страниц. Печатая в день на 5 страниц больше, чем планировала, она завершила работу на 2 дня раньше срока. Сколько страниц в день печатала машинистка.

Answer 1

2 дня - 48 часов

Пусть x страниц в день печатала машинистка.

А стала печатать на 5 стр больше (x+5)

Раньше она управилась бы за 200/x ч

А теперь за 200/(x+5) ч

Значит, 200/(х+5) - 48 = 200/x

 

Находишь x

Answer 2

Problem Analysis

To solve this problem, we need to determine how many pages the typist printed each day. We are given that the typist was supposed to print 200 pages in a certain amount of time, but she ended up finishing the work 2 days ahead of schedule by printing 5 pages more per day than planned.

Solution

Let's assume that the typist printed x pages per day, which is 5 pages more than planned. We can set up the following equation to represent the given information:

x * (number of days) = 200 pages

Since the typist finished the work 2 days ahead of schedule, the number of days can be represented as:

(number of days) = (planned number of days) - 2

Substituting this into the equation, we get:

x * ((planned number of days) - 2) = 200 pages

Now, we can solve for x by rearranging the equation:

x = 200 pages / ((planned number of days) - 2)

To find the value of x, we need to know the planned number of days. Unfortunately, this information is not provided in the question. Therefore, we cannot determine the exact number of pages the typist printed each day without this information.
