Answer:
Step-by-step explanation:
if 42% are men and 30% are women then the number of children is
(100 - 42 - 30)% of 49800, that is,
28% of 49800, that is,
28 × 49800 / 100 = 28 × 498 = 13944.

Total population in a town = 49800
Number of men in a town = 30% of 49800
= 42/100 * 49800 = 42 * 498 = 20916
Number of women in a town = 30% of 49800
= 30/100 * 49800
= 30 * 498
= 14940
Percentage of children in town = 100% - 42% - 30%
= 100% - 72%
= 28%
Number of children in a town = 28% of 49800
= 28/100 * 49800
= 28 * 498
= 13944
Number of children in a town = 13944
