Ex 11.2 class 8 maths ch 11 direct and inverse proportions talks about the topic of inverse proportion. We have provided the detailed solutions for this topic here on eSaral.

1. Inverse Proportion

Two quantities such as a and b are said to be in Inverse proportion if

• Increase in a decreases the b

• Decrease in a increases the b

However, the ratio of their respective values shall be the same.

• a and b will be in inverse proportion if k= ab

• In such a case if b₁, b₂ are the values of b corresponding to the values a₁, a₂ of a respectively then, a₁b₁ = a₂b₂ = k, 

• When two quantities a and b are in inverse proportion then they are written as a $\propto \frac{1}{b}$
