Question

Calculate A student is doing resistance exercise.

After one week, she can lift a weight of 2 kg. After four weeks, she can lift a weight of 3 kg. By what percentage has the weight that she can lift increased!

Answer 1

The weight that the student can lift has increased by 50%.

Step-by-step explanation:

To calculate the percentage increase in the weight that the student can lift, we can use the formula:

Percentage Increase = ((New Value - Old Value) / Old Value) * 100

Let's plug in the given values:

Old Value = 2 kg

New Value = 3 kg

Percentage Increase = ((3 - 2) / 2) * 100

= 50%

Therefore, the weight that the student can lift has increased by 50%.
