10.If two quantities x and y
inversely with each other, then-
O a.x/yremains constant.
O b.(x-y) remains constant.
O c. (x+y) remains constant.
O d.(xy) remains constant.​

Answer 1

xy = k, then x and y are said to vary inversely.

Step-by-step explanation:

Two quantities x and y are said to be in inverse proportion if an increase in x causes a proportional decrease in y (and vice-versa) in such a manner that the product of their corresponding values remains constant. That is, if xy = k, then x and y are said to vary inversely.
