Answer 2

Answer:

Step-by-step explanation:

In these type of questions the ratio must be equal

So, for that lets find the purest ratio you can find of the given x:y

x:y = 15:6 ( take 3 as common)

x:y = 5:2

Now the value of y asked is

x:y = 10:y = 5:2

x:y = 10:4 = 5:2

Then the value of y must be 4.
