Answer:_______________ |
| 1) The population of a village increases at the rate of 4% every year. If the present population is 11914,what will be the population after 2 years Answer: 12886 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 = 11914[1+(4÷100)]2 = 11914[1+0.04]2 = 11914(1.04)2 = 11914 x 1.0816 = |
11914| 2) The population of a village increases at the rate of 2% every year. If the present population is 42288,what will be the population after 3 years Answer: 44876 SOLUTION 1 : Given : Present population P = Rate of increase r = 2% Number of years n = 3 years The population after n years = P[1+(r÷100)]n = 42288[1+(2÷100)]3 = 42288[1+0.02]3 = 42288(1.02)3 = 42288 x 1.061208 = |
| 3) The population of a village increases at the rate of 5% every year. If the present population is 45114,what will be the population after 4 years Answer: 54836 SOLUTION 1 : Given : Present population P = Rate of increase r = 5% Number of years n = 4 years The population after n years = P[1+(r÷100)]n = 45114[1+(5÷100)]4 = 45114[1+0.05]4 = 45114(1.05)4 = 45114 x 1.21550625 = |
| 4) The population of a village increases at the rate of 5% every year. If the present population is 35383,what will be the population after 3 years Answer: 40960 SOLUTION 1 : Given : Present population P = Rate of increase r = 5% Number of years n = 3 years The population after n years = P[1+(r÷100)]n = 35383[1+(5÷100)]3 = 35383[1+0.05]3 = 35383(1.05)3 = 35383 x 1.157625 = |
| 5) The population of a village increases at the rate of 7% every year. If the present population is 49344,what will be the population after 4 years Answer: 64680 SOLUTION 1 : Given : Present population P = Rate of increase r = 7% Number of years n = 4 years The population after n years = P[1+(r÷100)]n = 49344[1+(7÷100)]4 = 49344[1+0.07]4 = 49344(1.07)4 = 49344 x 1.31079601 = |
| 6) The population of a village increases at the rate of 3% every year. If the present population is 25081,what will be the population after 3 years Answer: 27407 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 = 25081[1+(3÷100)]3 = 25081[1+0.03]3 = 25081(1.03)3 = 25081 x 1.092727 = |
| 7) The population of a village increases at the rate of 3% every year. If the present population is 18873,what will be the population after 2 years Answer: 20022 SOLUTION 1 : Given : Present population P = Rate of increase r = 3% Number of years n = 2 years The population after n years = P[1+(r÷100)]n = 18873[1+(3÷100)]2 = 18873[1+0.03]2 = 18873(1.03)2 = 18873 x 1.0609 = |
| 8) The population of a village increases at the rate of 2% every year. If the present population is 24000,what will be the population after 2 years Answer: 24970 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 = 24000[1+(2÷100)]2 = 24000[1+0.02]2 = 24000(1.02)2 = 24000 x 1.0404 = |
| 9) The population of a village increases at the rate of 2% every year. If the present population is 23536,what will be the population after 2 years Answer: 24487 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 = 23536[1+(2÷100)]2 = 23536[1+0.02]2 = 23536(1.02)2 = 23536 x 1.0404 = |
| 10) The population of a village increases at the rate of 5% every year. If the present population is 18368,what will be the population after 2 years Answer: 20251 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 = 18368[1+(5÷100)]2 = 18368[1+0.05]2 = 18368(1.05)2 = 18368 x 1.1025 = |
