A varies directly as B and inversely as C. A is 12 when B is 6 and C is 2. What is the value of A when B is 12 and C is 3? |

Answer» Solution :`AproptoB` and `Apropto 1/C` It MEANS ,`AproptoB/c IMPLIES A=(KB)/C` Here A varies directly as B but INVERSELY as C. Also it can vary as only directly or inversely as more than one quantities. `AproptoBC implies A=KBC` and `Apropto1/(BC)implies A=K/(BC)` |
