Note that women make up 25% of the total.
25% of total --> 5 units
100% of total --> 4 x 5 units = 20 units
Children --> 5 units + 56
Total number of people --> 20 units --> 3 units of men, 5 units women, 5 units children + 56 children
56 children --> 20 - 3 - 5 - 5 --> 7 units
7 units --> 56
1 unit --> 8
20 units --> 8 x 20 = 160
