Question

Jake is 2 5 25 years old. Next year, he'll be 2 6 26 years old. What is the percentage increase in Jake's age from last year?

Answer 1

4 %

Explanation:

initial age of Jake = 25 years

Final age of Jake = 26 years

Increase in Jake age = final age of Jake - initial age of Jake = 26 - 25 = 1 year

Percentage increase in the Jake's age

= increase in Jake's age / initial age x 100

=
`(1)/(25)* 100%`

= 4 %

Thus, the age of Jake is increased by 4%.

Answer 2

4%

Explanation:

We have been given that Jake is 25 years old. Next year, he'll be 26 years old.

To find the percentage increase in Jake's age from last year, we will use percentage decrease formula as our original value is less than new value.

`\text{Percentage decrease}=\frac{\text{Original-New}}{\text{Original}}*100`

Now let us substitute our given values in above formula.

`\text{Percentage decrease in Jake's age from last year}=(25-26)/(25)*100`

`\text{Percentage decrease in Jake's age from last year}=(-1)/(25)*100`

`\text{Percentage decrease in Jake's age from last year}=-1*4=-4`

Since our answer is a negative number then this is a percentage increase.

Therefore, there is 4% increase in Jake's age from last year.
