5. Variations Inverse Proportion Let us consider 2 quantities A and B If A increases then B decrease A x B K (Constant) .

6. Variations Indirect Proportion Example 1

7. 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

8. Thank You Arka Roy
