Explanation:

Correct option is 1: 1840

Explanation

The present population of the village is 15280
Male population increases by 25% i.e. 1/4
Female population increases by 15% i.e. 3/20
Population become after increment 18428
Concept used:
The Elimination Method for solving linear equations Calculation:
Let the present male & female population be M & F respectively.
According to the question,
M + F = 15280 ....(1)
Then,
After increment male population = M + M x 1/4 = 5M/4
After increment Female population = F + F x 3/20 = 23F/20
According to the question,
(5M/4)+(23F/20) = 18428 ...(2)
Now, solving (1) & (2), we get M = 8560 & F = 6720.
Now, the difference between the present male & female population = M - F = 8560 - 6720 = 1840. -The difference between the present population of males and females in the village is 1840.
