As given,

0.5

x

+

0.2

y

=18

it can be written as,

(

2

1

)

x

+

(

5

1

)

y

=18

⇒ 2x+5y=18

⇒ 5y=18−2x

Then, try plugging the value of x to get a corresponding y value that is a positive integer. Choose a value of x in such a way that subtraction of their twice from 18 be in multiple of 5.

Use x =4 for the eq. 5y=18−2x

Then, 5y=18−2×4 ; y=2

So, we got y =2 is an positive integer corresponding to the x=4

Hence,option D is correct.
