Q. If the population of a town is p in the beginning of any year then it becomes 3+2p in the beginning of the next year. If the population in the beginning of 2019 is 1000, then the population in the beginning of 2034 will be?
(997)2^14 + 3
(997)^15 – 3
(1003)^15 + 6
(1003)2^15 – 3
Answer: (1003)2^15 – 3
Solution:
Given as population of the town is p in the beginning of any year then it becomes 3+2p in the beginning of the next year
Population in 2019 = 1000 = (1003)*2^0 -3
So in 2020 it will be = 3 + 2*1000 = 2003 = (1003)*2^1 -3
In 2021 it will be = 3 + 2*2003 = 6009 = (1003)*2^2 -3
In 2022 it will be = 3 + 2*6009 = 12021 = ((1003)*2^3 –3
…
Thus in the year 2034 the population will be (1003)*2^15 -3
