If the AM is twice the GM of the numbers

a

and

b

, then

a: b

will be

View answer and explanation

Correct option: B

\frac{2+\sqrt{3}}{2-\sqrt{3}}

Option B (

\frac{2+\sqrt{3}}{2-\sqrt{3}}

) is correct because solving the given condition AM = 2GM leads to the ratio

a:b = (2+\sqrt{3}):(2-\sqrt{3})
