I am unable to see the perfect question
I am answering this with  the values i am able to see
It is given that velocity at highest point is half the initial velocity.
Velocity at highest point is given by
V=ucos(theta)
As given
V=1/2U
Hence,
ucos(theta)=1/2u
Cos(theta)=1/2
Theta=60
Max range =u²sin2(theta)/g
Substitute value of theta we get
Range =√3u/2g
