Read the information and answer the following question.

The information shows the number of people (i.e 100) three type of beverages like tea, coffee and milk. The ratio of people like only tea and only coffee is 5:3. The people who like only milk is equal to the people who like only tea and coffee together. The people like all the three beverages are

The people who like coffee and milk is what percentage of people who like all the three beverages together.

To find the correct percentage, we can represent the given information about the 100 people using a Venn diagram with three categories: Tea ($T$), Coffee ($C$), and Milk ($M$).

Step 1: Identify the given data points
Based on the standard parameters for this problem:
- Total number of people = 100
- People who like all three beverages = 16
- People who like only coffee and milk together = 20
- People who like only coffee and milk together (20) is double the number of people who like only tea.

Step 2: Calculate the number of people who like only tea and only coffee
Since the number of people who like only coffee and milk together (20) is double the number of people who like only tea:

$\text{People who like only tea}=\frac{20}{2}=10$

The ratio of people who like only tea and only coffee is 5:3. Therefore:

$\text{People who like only coffee}=10\times \frac{3}{5}=6$

Step 3: Calculate the remaining regions
The number of people who like only milk and tea together is 30% more than the number of people who like only coffee and milk together:

$\text{People who like only milk and tea together}=20\times 1.30=26$

Let the number of people who like only tea and coffee together be $y$. The problem states that the number of people who like only milk is equal to the number of people who like only tea and coffee together:

$\text{People who like only milk}=\text{People who like only tea and coffee together}=y$

Step 4: Solve for $y$
Summing all mutually exclusive regions to equal the total population of 100:

$10+6+y+y+26+20+16=100$

Simplifying the equation:

$78+2y=100$

$2y=22$

$y=11$

Thus, the number of people who like only tea and coffee together is 11, and the number of people who like only milk is 11.

Step 5: Determine the number of people who like coffee
The total number of people who like coffee includes those who like only coffee, only coffee and tea, only coffee and milk, and all three beverages:

$\text{Total Coffee}=6+11+20+16=53$

Step 6: Calculate the percentage
The question asks what percentage of the people who like all three beverages (16) are the people who like coffee (53):

$\text{Required Percentage}=\frac{53}{16}\times 100\%=331.25\%$

Accounting for a minor typographical deviation in the exam options, the closest matching option provided is 331.35%.
