Input: To calculate the percentage change from 6000 to 10000, we need to follow the below steps:

Step 1: Find the difference between the new value and the old value. In this case, the difference is 10000 - 6000 = 4000.

Step 2: Divide the difference by the old value and multiply by 100 to get the percentage change. So, (4000/6000) x 100 = 66.67%.

Step 3: The percentage change is positive, which means there is an increase in the value. Therefore, we can say that the value has increased by 66.67%.

In conclusion, the percentage change from 6000 to 10000 is 66.67%, which means the value has increased by 66.67%.
