Answer 2

Calculation of Words Read by Kroksha Ru

To determine the number of words read by Kroksha Ru in the morning, we need to consider the information given in the question.

1. Kroksha Ru read a total of 270 words in one day. 2. In the morning, he read 20 words less than during the day. 3. In the evening, he read 20 words more than in the morning.

Let's calculate the number of words read by Kroksha Ru in each period.

Calculation:

Let's assume the number of words read by Kroksha Ru in the morning is x.

According to the given information: - In the morning, he read 20 words less than during the day, so the number of words read during the day is x + 20. - In the evening, he read 20 words more than in the morning, so the number of words read in the evening is x + 20 + 20.

The total number of words read by Kroksha Ru in one day is 270, so we can set up the following equation:

x + (x + 20) + (x + 20 + 20) = 270

Simplifying the equation:

3x + 60 = 270

Subtracting 60 from both sides:

3x = 210

Dividing both sides by 3:

x = 70

Answer:

Based on the calculations, Kroksha Ru read 70 words in the morning, 90 words during the day, and 110 words in the evening.
