Ratio and Proportion made easy Lesson 7
Variations . 2 quantities may vary with one another directly or indirectly . Direct Proportion . Inverse Proportion
Variations Direct Proportion Let us consider 2 quantities A and B If A increases then B increase . If A increase by X% then B also increases . A-K (Constant)
Variations Direct Proportion Example 2 2 4
Variations Inverse Proportion Let us consider 2 quantities A and B If A increases then B decrease A x B K (Constant) .
Variations Indirect Proportion Example 1
Variations oint variation If B increases and C remains constant then A varies directly with B If C increases and B remains constant then A varies directly with C .If B and C both increases then A varies with B and C . If A remains constant then B varies inversely with C W1
