Maybe we solve it from the frame of upwards moving pulley and then equate velocities along the string.

Getting arctan[(√10-3)/2]
By this

I got an equation in terms of sin ϴ and cos ϴ and none of the options match with it. Maybe its wrong. I just used the usual, differentiating the length of rope equation.

@Chirag_Hegde
Yes same equation.

Getting
3sin@-2cos@=2√2?
@Viraam_Rao
Simplifying this gave me post #4

Exactly

I don't know about the answer, but this method seems very correct to me.
