ANSWER

st
we will make list of fractions and then compare them to make proportions.
150
9
=
50
3
⋯⋯(1)
105
9
=
35
3
⋯⋯(2)
150
105
=
50
35
=
10
7
⋯⋯(3)
1750
105
=
350
21
=
50
3
⋯⋯(4)
1750
150
=
350
30
=
35
3
⋯⋯(5)
From (1) and (4)
150
9
=
1750
105
and
9
150
=
105
1750
⇒9:150::105:1750
and 150:9::1750:105
From (2) and (5)
105
9
=
1750
150
and
9
105
=
150
1750
⇒9:105::150:1750
and 105:9::1750:150
So, possible proportions are
⇒9:150::105:1750
150:9::1750:105
9:105::150:1750
and 105:9::1750:150
