Answer 2

Heya User,

--> Consider the roots..
Since the ratio is 3 : 2  :-> the roots can be written as :->
            --> 3a  || 2a

--> We know that sum of roots = - [ co-eff x ] / [ coeff x² ]
-->    and that product of roots =  constant term / [ coeff x² ]

Hence,
--> 3a + 2a = -m / 12
=> a = -m / 60

Further,
--> ( 3a )( 2a ) = 5 / 12
=> 6 [ m² / 3600 ] = 5 / 12
=> m² = 250
=> m = 5√10   ^_^ ^_^ ^_^ 0_0 0_0 0_0 

=> The option ( i ) is correct
