In a village of 50 persons; 10 immigrated; 25 died and 5 emigrated in year. Determine the total population?

A. 10
B. 20
C. 30
D. 50

Correct Answer:

Option C – 30

Explanation

Emigrants are people who move in to settle in a particular region (increasing the new population)
Immigrants are people who move out of a particular region to another place. (Reducing the old place of residence)

50 + 10 = 60 new population

Less number of dead people and immigrants; = 30

60 – 30 = 30
