There were 200 people in a soccer club.25 people left the club in the first week.47 people left the club in the second week.Find the percentage decrease in the number of people in the club.

Step 1: Find the total number of people who left the club.

This is done by adding the number of people who left in the first week to the number who left in the second week.

25 (first week) + 47 (second week) = 72 people

Step 2: Calculate the percentage decrease in the number of people in the club.

The formula for percentage decrease is:

(Decrease in value/Original value) * 100

So, the decrease in value is the number of people who left the club, which is 72. The original value is the original number of people in the club, which is 200.

So, the percentage decrease is:

(72/200) * 100 = 36%

So, the percentage decrease in the number of people in the club is 36%.
