Answer 2

The value of y is 225.

Step-by-step explanation:

Given, x varies directly to y.

So, x = ky................(i)

Where k = constant

Given, x = 10 and y = 150

Plug the values of x and y in equation(i),

10 = k (150)

=> k = $\frac{10}{150} = \frac{1}{15}$

If x = 15,

15 = $\frac{1}{15}\times y$

=> y = 15 x 15 = 225

Hence, the value of y is 225.
