Answer 1

Answer:

correct option 1)

Step-by-step explanation:

Correct option is

A

i.ii

(i)

xy=(4)(6)=24

xy=(3)(8)=24

xy=(12)(2)=24

xy=(1)(24)=24

Here, x and y varies inversely, since product of xy in all cases are same.

(ii)

xy=(5)(20)=100

xy=(20)(5)=100

xy=(10)(10)=100

xy=(4)(25)=100

Here, x and y varies inversely, since product of xy in all cases are same.

(iii)

xy=(4)(9)=36

xy=(3)(12)=36

xy=(6)(8)=48

xy=(1)(36)=36

Here, x and y do not vary inversely, since product of xy in all cases are not same.

(iv)

xy=(9)(8)=72

xy=(24)(3)=72

xy=(15)(4)=60

xy=(3)(25)=75

Here, x and y do not vary inversely, since product of xy in all cases are not same.
