Answers
STEP 1: Find the decrease in males:
Males = 2440 (Given)
10% X 2440 =244
Males after decreased = 2440 - 244 = 2196
-------------------------------------------------------------------------------------------
STEP 2: Find the increase in females:
Females = 3560
5% x 3560 = 0.05 x 3560 = 178
Females after increased = 3560 + 178 = 3738
-------------------------------------------------------------------------------------------
STEP 4: Find population change:
Before : 2440 + 3560 = 6000
After: 2196 + 3738 = 5934
6000 - 5934 = 66
-------------------------------------------------------------------------------------------
STEP 5: Find percentage change:
Percentage change = 66/6000 x 100 = 1.1%
-------------------------------------------------------------------------------------------
Answer: The population decreased by 1.1%
