Answer / pramit dutta
i think the question is incomplete ,
we know n=(1-s)ns , so, ns=(120*50)/4=1500 rpm.
so we need to know the slip of motor then we find answer.

Answer / netserab
first v 120f/p i.e. when 120 constant
f given ferquency
p is number of poles
then we have 4 poles on the sator and 6 poles on the
roter 120x50/3/2=1000
