Answer 1

Class A :
`y= (3x)/(5)`

Class B :
`y=(1)/(2) x`

Explanation:

Class A :

Let the amount of Salt in the solution be represented by y as, it is supposed to be the independent variable.

Similarly let the amount of Water in the solution be x

As we are given that for Class A , The ratio of salt content to water content is 3 to 5

Hence

`(y)/(x)=(3)/(5)`

Multiplying both sides by x we get

`y= (3x)/(5)`

Class B :

Let the amount of Salt in the solution be represented by y as, it is supposed to be the independent variable.

Similarly let the amount of Water in the solution be x

As we are given that for Class A , The ratio of salt content to water content is 2 to 4

Hence

`(y)/(x)=(2)/(4)`

multiplying both sides by x we get

`y=(1)/(2) x`
