Section C (20 marks)

Q15. Females = 7 845 230 − 3 920 415 = 3 924 815
Difference = 3 920 415 − 3 924 815 = −4 400 → actually females are more by 4 400.
Correction: Males 3 920 415, Females 3 924 815, so females are more by 3 924 815 − 3 920 415 = 4 400. Question asks "more males than females" → answer is 0 (males are not more). But if interpreted as absolute difference: 4 400 more females. Mark as: Males − Females = −4 400, so 4 400 more females.
