108

- Let's call the second number "x".

- The first number is three times the second number, so it's "3x".

- The average of the two numbers is given as 72.

- So, we write the equation for the average: (x + 3x)/2 = 72.

- Simplify the equation: 4x/2 = 72 ? 2x = 72 ? x = 36.

- The first number "3x" thus becomes 3 * 36 = 108.

- Therefore, the first number is 108.

- Option:1, 108

- Option:2, 54

- Option:3, 36

- Option:4, 64
