To determine the percentage of students playing games who were boys, let's follow these steps:

1. Identify Total Students Playing Games: The table shows that the total number of students who spent more time playing games on their tablets is 192.

2. Identify Boys Playing Games: According to the table, the number of boys who spent more time playing games is 138.

3. Calculate the Percentage: The percentage of boys who played games compared to the total number of students playing games can be found using the formula for percentage:

[tex]\[ \text{Percentage} = \left( \frac{\text{Number of Boys Playing Games}}{\text{Total Students Playing Games}} \right) \times 100 \][/tex]

Plugging in the numbers:

[tex]\[ \text{Percentage} = \left( \frac{138}{192} \right) \times 100 \][/tex]

4. Perform the Calculation: Calculating this gives us:

[tex]\[ \text{Percentage} \approx 71.875\% \][/tex]

Therefore, the percentage of students who spent more time playing games on their tablets and were boys is approximately [tex]\( 72\% \)[/tex].

Given the choices, the correct answer is:

3) 72
