Answer:_______________ |
| 1) The population of a village increases at the rate of 6% every year. If the present population is 48498,what will be the population after 2 years Answer: 54492 SOLUTION 1 : Given : Present population P = Rate of increase r = 6% Number of years n = 2 years The population after n years = P[1+(r÷100)]n = 48498[1+(6÷100)]2 = 48498[1+0.06]2 = 48498(1.06)2 = 48498 x 1.1236 = |
48498| 2) The population of a village increases at the rate of 4% every year. If the present population is 40561,what will be the population after 3 years Answer: 45626 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 = 40561[1+(4÷100)]3 = 40561[1+0.04]3 = 40561(1.04)3 = 40561 x 1.124864 = |
| 3) The population of a village increases at the rate of 4% every year. If the present population is 42549,what will be the population after 2 years Answer: 46021 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 = 42549[1+(4÷100)]2 = 42549[1+0.04]2 = 42549(1.04)2 = 42549 x 1.0816 = |
| 4) The population of a village increases at the rate of 6% every year. If the present population is 35621,what will be the population after 3 years Answer: 42425 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 = 35621[1+(6÷100)]3 = 35621[1+0.06]3 = 35621(1.06)3 = 35621 x 1.191016 = |
| 5) The population of a village increases at the rate of 5% every year. If the present population is 27275,what will be the population after 2 years Answer: 30071 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 = 27275[1+(5÷100)]2 = 27275[1+0.05]2 = 27275(1.05)2 = 27275 x 1.1025 = |
