In which of the following tables x and y vary inversely:
(i)
X | 4 | 3 | 12 | 1 |
Y | 6 | 8 | 2 | 24 |
(ii)
X | 5 | 20 | 10 | 4 |
Y | 20 | 5 | 10 | 25 |
(iii)
X | 4 | 3 | 6 | 1 |
Y | 9 | 12 | 8 | 36 |
(iv)
X | 9 | 24 | 15 | 3 |
Y | 8 | 3 | 4 | 25 |

(ii) x varies inversely as y since one quantiy is inceasing and other is decreasing in the same proportion.
(iii) x doesn’t varies inversely as y since the quanties are not varying in same proportion
