Answer: " "20%

#### Explanation:

You need to use the following equation:

"% change" = "change (increase or decrease)"/"the original" times 100%

The difference between the two marks is $14$. His original mark was $70$. This means we divide $14$ by $70$, and multiply by 100%.

We get 20% as our percentage increase.
