[Haryana Grammen Bank (PO), 2009]

12:11

11:9

9:10

Cannot be determined

None of these

Explanation

let the two numbers be x and y

Then,

$\Rightarrow \frac{3}{4} \times x = \frac{5}{6} \times y \Rightarrow \frac{x}{y} = \frac{5}{6} \times \frac{4}{3} = \frac{20}{18} = 10 : 9$

Hence, Option D is correct.
