A. 800
B. 5000
C. 5060
D. 6000
Answer : B. 5000
Explanation:
Let the number of men in the village is x.
Number of women in the village is (8000 – x)
If 6% men and 10% women are added population becomes 8600,
x(106 / 100) + (8000 – x) (110 / 100) = 8600
[(110 – 106) / 100] * x = 8800 – 8600
x = 200 * 100 / 4 = 5000
Hence the number of men in the village is 5000.
