Calculation of Total Participants in the Sports Competition

To calculate the total number of participants in the sports competition, we can add up the number of participants on each day.

In the first day, 34% of all participants took part. In the second day, 30% of all participants participated. And on the third day, the remaining 180 people participated.

Let's calculate the total number of participants step by step:

1. Calculate the number of participants on the first day: - Let's assume the total number of participants as 'x'. - 34% of 'x' participated on the first day, which is 0.34 * x. - So, the number of participants on the first day is 0.34 * x.

2. Calculate the number of participants on the second day: - 30% of 'x' participated on the second day, which is 0.30 * x. - So, the number of participants on the second day is 0.30 * x.

3. Calculate the number of participants on the third day: - The remaining 180 people participated on the third day.

4. Calculate the total number of participants: - The total number of participants is the sum of the participants on each day. - Total participants = (0.34 * x) + (0.30 * x) + 180.

Let's solve the equation to find the value of 'x':

(0.34 * x) + (0.30 * x) + 180 = x

Simplifying the equation:

0.34x + 0.30x + 180 = x

Combining like terms:

0.64x + 180 = x

Subtracting 0.64x from both sides:

180 = 0.36x

Dividing both sides by 0.36:

x = 500

Therefore, the total number of participants in the sports competition is 500.
