Answer:_______________ |
| 1) The population of a village increases at the rate of 2% every year. If the present population is 33212,what will be the population after 2 years Answer: 34554 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 = 33212[1+(2÷100)]2 = 33212[1+0.02]2 = 33212(1.02)2 = 33212 x 1.0404 = |
33212| 2) The population of a village increases at the rate of 3% every year. If the present population is 20125,what will be the population after 4 years Answer: 22651 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 = 20125[1+(3÷100)]4 = 20125[1+0.03]4 = 20125(1.03)4 = 20125 x 1.12550881 = |
| 3) The population of a village increases at the rate of 3% every year. If the present population is 36536,what will be the population after 4 years Answer: 41122 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 = 36536[1+(3÷100)]4 = 36536[1+0.03]4 = 36536(1.03)4 = 36536 x 1.12550881 = |
| 4) The population of a village increases at the rate of 3% every year. If the present population is 46599,what will be the population after 4 years Answer: 52448 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 = 46599[1+(3÷100)]4 = 46599[1+0.03]4 = 46599(1.03)4 = 46599 x 1.12550881 = |
| 5) The population of a village increases at the rate of 6% every year. If the present population is 13843,what will be the population after 2 years Answer: 15554 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 = 13843[1+(6÷100)]2 = 13843[1+0.06]2 = 13843(1.06)2 = 13843 x 1.1236 = |
| 6) The population of a village increases at the rate of 6% every year. If the present population is 12243,what will be the population after 4 years Answer: 15457 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 = 12243[1+(6÷100)]4 = 12243[1+0.06]4 = 12243(1.06)4 = 12243 x 1.26247696 = |
| 7) The population of a village increases at the rate of 3% every year. If the present population is 19025,what will be the population after 4 years Answer: 21413 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 = 19025[1+(3÷100)]4 = 19025[1+0.03]4 = 19025(1.03)4 = 19025 x 1.12550881 = |
| 8) The population of a village increases at the rate of 4% every year. If the present population is 26758,what will be the population after 4 years Answer: 31303 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 = 26758[1+(4÷100)]4 = 26758[1+0.04]4 = 26758(1.04)4 = 26758 x 1.16985856 = |
| 9) The population of a village increases at the rate of 4% every year. If the present population is 17030,what will be the population after 4 years Answer: 19923 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 = 17030[1+(4÷100)]4 = 17030[1+0.04]4 = 17030(1.04)4 = 17030 x 1.16985856 = |
| 10) The population of a village increases at the rate of 2% every year. If the present population is 45190,what will be the population after 3 years Answer: 47956 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 = 45190[1+(2÷100)]3 = 45190[1+0.02]3 = 45190(1.02)3 = 45190 x 1.061208 = |
