Answer:_______________ |
| 1) The population of a village increases at the rate of 6% every year. If the present population is 20460,what will be the population after 3 years Answer: 24368 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 = 20460[1+(6÷100)]3 = 20460[1+0.06]3 = 20460(1.06)3 = 20460 x 1.191016 = |
20460| 2) The population of a village increases at the rate of 4% every year. If the present population is 40791,what will be the population after 2 years Answer: 44120 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 = 40791[1+(4÷100)]2 = 40791[1+0.04]2 = 40791(1.04)2 = 40791 x 1.0816 = |
| 3) The population of a village increases at the rate of 3% every year. If the present population is 44265,what will be the population after 2 years Answer: 46961 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 = 44265[1+(3÷100)]2 = 44265[1+0.03]2 = 44265(1.03)2 = 44265 x 1.0609 = |
| 4) The population of a village increases at the rate of 5% every year. If the present population is 35036,what will be the population after 4 years Answer: 42586 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 = 35036[1+(5÷100)]4 = 35036[1+0.05]4 = 35036(1.05)4 = 35036 x 1.21550625 = |
| 5) The population of a village increases at the rate of 3% every year. If the present population is 31458,what will be the population after 4 years Answer: 35406 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 = 31458[1+(3÷100)]4 = 31458[1+0.03]4 = 31458(1.03)4 = 31458 x 1.12550881 = |
| 6) The population of a village increases at the rate of 4% every year. If the present population is 40232,what will be the population after 4 years Answer: 47066 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 = 40232[1+(4÷100)]4 = 40232[1+0.04]4 = 40232(1.04)4 = 40232 x 1.16985856 = |
| 7) The population of a village increases at the rate of 4% every year. If the present population is 32409,what will be the population after 3 years Answer: 36456 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 = 32409[1+(4÷100)]3 = 32409[1+0.04]3 = 32409(1.04)3 = 32409 x 1.124864 = |
| 8) The population of a village increases at the rate of 3% every year. If the present population is 37089,what will be the population after 2 years Answer: 39348 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 = 37089[1+(3÷100)]2 = 37089[1+0.03]2 = 37089(1.03)2 = 37089 x 1.0609 = |
| 9) The population of a village increases at the rate of 2% every year. If the present population is 24635,what will be the population after 4 years Answer: 26666 SOLUTION 1 : Given : Present population P = Rate of increase r = 2% Number of years n = 4 years The population after n years = P[1+(r÷100)]n = 24635[1+(2÷100)]4 = 24635[1+0.02]4 = 24635(1.02)4 = 24635 x 1.08243216 = |
| 10) The population of a village increases at the rate of 3% every year. If the present population is 44534,what will be the population after 4 years Answer: 50123 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 = 44534[1+(3÷100)]4 = 44534[1+0.03]4 = 44534(1.03)4 = 44534 x 1.12550881 = |
