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.
