In a test, the marks obtained by $\text{E}$ is $30\%$ more than the marks obtained by $\text{F}$. If $\text{F}$ scored $20$ marks, how many marks did $\text{E}$ score?

Given parameters:
* Marks scored by $\text{F}=20$
* Marks scored by $\text{E}$ is $30\%$ more than $\text{F}$ 's score.

Calculate the additional marks scored by $\text{E}$:

$$\text{Additional Marks}=30\%\text{ of }20=\frac{30}{100}\times 20=6$$

Now, compute $\text{E}$ 's total score:

$$\text{E’s marks}=\text{F’s marks}+\text{Additional Marks}=20+6=26$$
