Answer:_______________ |
| 1) The population of a village increases at the rate of 3% every year. If the present population is 31241,what will be the population after 3 years Answer: 34138 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 = 31241[1+(3÷100)]3 = 31241[1+0.03]3 = 31241(1.03)3 = 31241 x 1.092727 = |
31241| 2) The population of a village increases at the rate of 6% every year. If the present population is 14377,what will be the population after 4 years Answer: 18151 SOLUTION 1 : Given : Present population P = Rate of increase r = 6% Number of years n = 4 years The population after n years = P[1+(r÷100)]n = 14377[1+(6÷100)]4 = 14377[1+0.06]4 = 14377(1.06)4 = 14377 x 1.26247696 = |
| 3) The population of a village increases at the rate of 3% every year. If the present population is 17656,what will be the population after 4 years Answer: 19872 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 = 17656[1+(3÷100)]4 = 17656[1+0.03]4 = 17656(1.03)4 = 17656 x 1.12550881 = |
| 4) The population of a village increases at the rate of 6% every year. If the present population is 49115,what will be the population after 4 years Answer: 62007 SOLUTION 1 : Given : Present population P = Rate of increase r = 6% Number of years n = 4 years The population after n years = P[1+(r÷100)]n = 49115[1+(6÷100)]4 = 49115[1+0.06]4 = 49115(1.06)4 = 49115 x 1.26247696 = |
| 5) The population of a village increases at the rate of 4% every year. If the present population is 39762,what will be the population after 2 years Answer: 43007 SOLUTION 1 : Given : Present population P = Rate of increase r = 4% Number of years n = 2 years The population after n years = P[1+(r÷100)]n = 39762[1+(4÷100)]2 = 39762[1+0.04]2 = 39762(1.04)2 = 39762 x 1.0816 = |
| 6) The population of a village increases at the rate of 2% every year. If the present population is 31939,what will be the population after 2 years Answer: 33229 SOLUTION 1 : Given : Present population P = Rate of increase r = 2% Number of years n = 2 years The population after n years = P[1+(r÷100)]n = 31939[1+(2÷100)]2 = 31939[1+0.02]2 = 31939(1.02)2 = 31939 x 1.0404 = |
| 7) The population of a village increases at the rate of 4% every year. If the present population is 35219,what will be the population after 3 years Answer: 39617 SOLUTION 1 : Given : Present population P = Rate of increase r = 4% Number of years n = 3 years The population after n years = P[1+(r÷100)]n = 35219[1+(4÷100)]3 = 35219[1+0.04]3 = 35219(1.04)3 = 35219 x 1.124864 = |
