• # question_answer 25) Which of the following tables shows the inverse proportion? (i) x 6 12 30 48 y 250 125 50 31.25 (ii) x 115 130 145 160 y 615 600 585 570 (iii) x 50 100 300 1200 y 300 150 100 75 A)  Only (i)                      B)  Both (i) and (ii)          C)  Both (ii) and (iii)        D)  None of these

(i) For inverse proportion, xy= constant Now, $6\times 250=1500$, $12\times 125=1500,30\times 50=1500$ And $48\times 31.25=1500$ $\therefore$ The data is in inverse proportion. (ii) $115\times 615=70725,$ $130\times 600=78000$ $\therefore$ The data is not in inverse proportion. (iii) $50\times 300=15000$, $100\times 150=15000$, And $300\times 100=30000$ $\therefore$ The data is not in inverse proportion.
