To be 120% increase means, 120% increase is 2.2 times as strong.
In the given question, we have to explain what does it mean to be 150% of something.
A figure or ratio stated as a fraction of 100 is called a percentage. It is frequently indicated by the percent sign, "%."
When something gets 120% increase, you must also factor in its original 100% strength, which is expressed as follows:
120% + 100% = 220%
Additionally, keep in mind that "percent" refers to anything relative to 100, therefore we can rephrase the percentage as a number:
220% = 220/100 = 2.2
Therefore, something that is 120% higher is 2.2 times as strong.
