Answer:
The weekly savings of first person = $900
The weekly savings of second person = $700.
Step-by-step explanation:
Let us assume the income of first person = $ m
Now, as the difference in the income is $200.
⇒ And the income of first person - income of first person = $200
⇒ Income of second person = m - $200
So, according to the question:
Ratio of Income of First person : Second Person's Income = 9: 7
or, m : ( m - 200) = 9: 7
[tex]\implies \frac{m}{m - 200 } = \frac{9}{7}[/tex]
[tex]7 \times m = (m - 200) \times 9\\\implies 7 m = 9m - 1800\\\implies 7m - 9m = -1800\\\implies -2m = -1800\\m = \frac{1800}{2} = 900[/tex]
or,m = $900
Hence, the weekly savings of first person = $900
and the weekly savings of second person = m - 200 = $900 - 200 = $700.
