12. If two quantities x and y are in inverse proportion, then the relation between x and y must be (A) xy = 1 = (B) xy = k, k being a constant = (C) 1 {D)=k, k being a constant. (if you will give wrong answer report + block)

Answer» Since, two quantities x and y are SAID to be in Inverse PROPORTION, if an INCREASES in x cause a proportional decreases in y and vice-versa, in such a manner that the product of their CORRESPONDING values remains constantmark me as BRANLIST
