Step-by-step explanation:
x and y are in direct proportion.
[tex]x = k \times y \: \: \: \: \: \: \: (where \: \: k \: \: \: is \: a \: \: variation \: \: constant)[/tex]
If, x = 20 and y=25 then,
[tex]20 = k \times 25[/tex]
[tex]k = \frac{20}{25} [/tex]
[tex]k = \frac{4}{5} [/tex]
If, x=32 and k = 4/5 ,then
[tex]x = k \times y[/tex]
[tex]32 = \frac{4}{5} \times y[/tex]
[tex]32 \times \frac{5}{4} = y[/tex]
[tex] 8 \times 5 = y[/tex]
[tex]y = 40[/tex]
The value of y is 40.
