400 are unemployed and 300 are somnambulists. So 200 are employed and 300 are Non-somnambulists.
Half of the somnambulists are unemployed = 150. So employed somnambulists = 300 -150 = 150.
Employed and not somnambulists = 200 - 150 = 50. Hence the answer is A.
Half of the somnambulists are unemployed = 150. So employed somnambulists = 300 -150 = 150.
Employed and not somnambulists = 200 - 150 = 50. Hence the answer is A.
