  • D 2563 ✔ ✖
Correct Answer: Option B

Explanation


To solve this problem, you can set up an equation using the given information. 
Let X be the population of the village in the beginning. 
Then:

X * (1 - 0.05) * (1 - 0.15) = 3553
X * 0.95 * 0.85 = 3553
X = (3553 / (0.95 * 0.85))
X = (3553 / (0.8075))
X = 4400

Therefore, the population of the village in the beginning was 4400.
