The Correct Option is B

Solution and Explanation

from the equation xy=2\frac{x}{y} = 2, we can use xx in terms of yy:

x=2yx = 2y

Now, to find the value of 8ya\frac{8y}{a}, we need to relate aa to yy. If we assume a=xa = x then:

8ya=8y2y=82=4\frac{8y}{a} = \frac{8y}{2y} = \frac{8}{2} = 4

So, the value of 8ya\frac{8y}{a} is 4.


The correct option is (B): 4
