If two quantities are in inverse proportion, then the relation between two pairs is:

Class 8Direct and Inverse ProportionsDirect and Inverse Proportions

Ax1 times y1 = x2 times y2
B $\frac{x _{1}}{y _{1}} = \frac{x _{2}}{y _{2}}$
C $x 1 + y 1 = x 2 + y 2$
D $\frac{x _{1}}{x _{2}} = \frac{y _{1}}{y _{2}}$

Step-by-Step Solution

In inverse proportion the product xy is constant, so x1 times y1 = x2 times y2 = k.

Answer: A) x1 times y1 = x2 times y2
