प्रश्न
If xy = 10, then x and y vary ______ with each other.
उत्तर
If xy = 10, then x and y vary inversely with each other.
Explanation:
Given, xy = 10
∴ `x = 10/y`
Hence, x and y vary inversely with each other.
Notes
Since, in case, if y1, y2 are the values of y corresponding to the values x1, x2 of x, respectively, then `x_1y_1 = x_2y_2` or `x_1/x_2 = y_1/y_2`
