Question

What is the percent increase from 0 to 19?

Answer 1

Hint: We are given a question asking us to tell the percent increase from 0 to 19. Here the original number is 0 and the new number is 19. The percent increase will be found by taking the ratio of the difference of the original number and the new number and the new number and then multiplying the ratio by 100, mathematically it can be represented by \[\dfrac{\text{Difference}}{\text{New number}}\times 100\]. After solving the expression, we will get the percent increase. Hence, we will have the required percentage.

Complete step-by-step answer:
According to the given question, we are asked to find the percentage increase from 0 to 19.
Here, we have the original number is 0 and the new number is 19. And we have to find the percent increase.
The general equation we know for calculating the percent increase is, \[\dfrac{\text{Difference}}{\text{Original number}}\times 100\].
But in this case, the denominator will be a 0 as the original number is 0 and having 0 in the denominator gives an undefined value and so cannot be computed further.
So, we will modify the formula a bit and we get,
\[\dfrac{\text{Difference}}{\text{New number}}\times 100\]
We will now substitute all the known values in the above expression and we get,
\[\Rightarrow \dfrac{19-0}{19}\times 100\]
Solving the above expression further and reducing the expression we get,
\[\Rightarrow \dfrac{19}{19}\times 100\]
\[\Rightarrow 1\times 100=100\%\]
So, there is a hundred percent increase in the number from 0 to 19. 0 means null or void. So, any jump from to any number will give a hundred percent increase only.
Therefore, from 0 to 19 there is a hundred percent increase.

Note: The given question if not understood properly can create chances for fatal mistakes. When a number increases from 1 to any number say 10, we say that the new number is ten times than the original number. But this cannot be the case when a number is increased from 0 to any number, since 0 does not come as a multiple of any number. In order to increase the value from 0, we have to add numbers to it. This question is tricky and should be carefully solved.
