125% of what number is 20

16

Step-by-step explanation:

We can rewrite this as 125/100 · x = 20

This works because a percentage is out of 100, which means 125% is 125/100. "Of" usually means multiplied, and "what number" is the variable.

Now we can simplify this

125/100 · x = 20

5/4 · x = 20

x = 16

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted
