Question and options
The population of a village is 5000. If in a year, the number of males were to increase by 5% and that of females by 3% annually, the population would grow to 5202 at the end of the year. If M is the number of males and F is the number of females in the village, then (M,F) =
- (3000, 2000)
- (2800, 2200)
- (2600, 2400)
- (2700, 2300)
Answer and explanation
Correct answer: C - (2600, 2400)
M+F = 5000 and 0.05M+0.03F = 202. Since 0.03 x 5000 = 150, 0.02M = 52, so M = 2600 and F = 2400.
