Answer:_______________ |
| 1) The population of a village increases at the rate of 4% every year. If the present population is 33970,what will be the population after 4 years Answer: 39740 SOLUTION 1 : Given : Present population P = Rate of increase r = 4% Number of years n = 4 years The population after n years = P[1+(r÷100)]n = 33970[1+(4÷100)]4 = 33970[1+0.04]4 = 33970(1.04)4 = 33970 x 1.16985856 = |
33970| 2) The population of a village increases at the rate of 3% every year. If the present population is 43462,what will be the population after 3 years Answer: 47492 SOLUTION 1 : Given : Present population P = Rate of increase r = 3% Number of years n = 3 years The population after n years = P[1+(r÷100)]n = 43462[1+(3÷100)]3 = 43462[1+0.03]3 = 43462(1.03)3 = 43462 x 1.092727 = |
| 3) The population of a village increases at the rate of 7% every year. If the present population is 46301,what will be the population after 3 years Answer: 56721 SOLUTION 1 : Given : Present population P = Rate of increase r = 7% Number of years n = 3 years The population after n years = P[1+(r÷100)]n = 46301[1+(7÷100)]3 = 46301[1+0.07]3 = 46301(1.07)3 = 46301 x 1.225043 = |
| 4) The population of a village increases at the rate of 6% every year. If the present population is 24324,what will be the population after 3 years Answer: 28970 SOLUTION 1 : Given : Present population P = Rate of increase r = 6% Number of years n = 3 years The population after n years = P[1+(r÷100)]n = 24324[1+(6÷100)]3 = 24324[1+0.06]3 = 24324(1.06)3 = 24324 x 1.191016 = |
| 5) The population of a village increases at the rate of 3% every year. If the present population is 47141,what will be the population after 4 years Answer: 53058 SOLUTION 1 : Given : Present population P = Rate of increase r = 3% Number of years n = 4 years The population after n years = P[1+(r÷100)]n = 47141[1+(3÷100)]4 = 47141[1+0.03]4 = 47141(1.03)4 = 47141 x 1.12550881 = |
| 6) The population of a village increases at the rate of 3% every year. If the present population is 19726,what will be the population after 4 years Answer: 22202 SOLUTION 1 : Given : Present population P = Rate of increase r = 3% Number of years n = 4 years The population after n years = P[1+(r÷100)]n = 19726[1+(3÷100)]4 = 19726[1+0.03]4 = 19726(1.03)4 = 19726 x 1.12550881 = |
| 7) The population of a village increases at the rate of 5% every year. If the present population is 36029,what will be the population after 2 years Answer: 39722 SOLUTION 1 : Given : Present population P = Rate of increase r = 5% Number of years n = 2 years The population after n years = P[1+(r÷100)]n = 36029[1+(5÷100)]2 = 36029[1+0.05]2 = 36029(1.05)2 = 36029 x 1.1025 = |
