Question

plz friends tell me how this is the answers of the questions prove it plz... for me..i hv ticked the right option

Answer 1

Hey MATE!

1) 1/x is directly proportional to 1/y (given)

Therefore, obviously the 1st option is correct as it is already said in the question and they can't be indirectly proportional.

2) x and y vary inversely.

Therefore x is inversely proportional to 1/y.

To remove proportionality sign we introduce a constant K.

Now
$x = \frac{k}{y} \\ \\ xy \: = \: k$

Hope it helps
