Option 2 : 8 : 13

Calculation:

Total number of students who scored marks less than 60% = (10 + 30) = 40

Total number of students who scored marks 80% and above = (40 + 25) = 65

The ratio of the number of students who scored marks less than 60% to the number of students who scored marks 80% and above = (40 : 65)

⇒ 8 : 13

∴ The required ratio is 8 : 13
