Option 5 : 2 : 3

**Given:**

Total number of students = 750

**Calculation:**

The number of students who like all three colors = 100 students

and the number of students who like only green color = 150 students

Now, required ratio = 100 : 150

⇒ 2 : 3

**∴ The ratio of the number of students who like all three colors to the number of students who like only green color is 2 : 3.**
