Variations Direct Proportion Example 2 2 4
Variations Inverse Proportion Let us consider 2quantities A and B If A increases then B decrease Ax B K (Constant) .
Variations Indirect Proportion Example 2 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
