Answer:
270 people
Step-by-step explanation:
If we think of the ratio as "parts", it becomes very easy!
- 3 parts get their news from Frontbook
- 7 parts get their news from elsewhere
In total there are 3 + 7 = 10 parts
Really, in the town there are 900 people so each part is people
And we know 3 parts get their news from Frontbook, so 3 parts is people
2838=total
Women = 3X +5
Men = 4(3x+5)-3
Children= x
Men= 12x+17
Total= 16X +23
16x + 23 = 2838
16x = 2815
X = 2815/16
