Answer:

(i) 96 male

(ii) 12 female staff

Step-by-step explanation:

Population = 240

220 students, 20 staff

40% of the population is male (student and staff)

55% of the population are female students

40 + 55 = 95%

95% of the whole population is known, 5% are the female staff based on the problem.

240 x 0.4 = 96

240 x 0.05 = 12
