| Column I | Column II | |
| 1. | X and y vary inversely to each other | A. \[\frac{x}{y}\]= Constant |
| 2. | Mathematical representation of inverse variation of quantities p and q | B. y will increase in proportion |
| 3. | Mathematical representation of direct variation of quantities m and n | C. xy= constant |
| 4. | When =5,y=2.5and when y=5,x=10 | D. \[p\propto \frac{1}{q}\] |
| 5. | When x = 10, y = 5 and when x = 20, y = 2.5 | E. y will decrease in proportion |
| 6. | x and y vary directly with each other | E x and y directly proportional |
| 7. | If x and y vary inversely then on decreasing x | G. \[m\text{ }\alpha \,n\] |
| 8. | If z and y vary directly then on decreasing x. | H. x and y vary inversely |
| \[I.p\propto q\] | ||
| \[J.m\propto \frac{1}{n}\] |
Answer:
\[1.\to H,\] \[2.\to D,\] \[3.\to G,\] \[4.\to F,\] \[5.\to C,\] \[6.\to A,\] \[7.\to B,\] \[8.\to E.\]
