This happens because population is both a consumer and producer. There are two schools of thought. One which treats population as a resource, and the other as a burden to the society. The truth, in fact, lies somewhere in between. The interplay of factors responsible for population growth and those for development decide the resourcefulness of population.
20. Why is it said that population is one resource that never depletes?
1) because other resources deplete
2) because population is an ever-increasing phenomenon -Answer
3) because population is seen as a resource
4) because it is an easily available commodity
5) None of these
21. Why population is at the same time treated as a resource and also as a burden to the society?

a) 26 B)25 c)5 d)27
Solution: for every hour water in tank in B is doubled,
Let the duration to fill the tank B is x hours.
x/32 part of water in tank of B is filled in 21 hours,
Next hour it is doubled so,
2*(x/32) part i.e (x/16) part is filled in 22 hours,
Similarly (x/8)th part in 23 hours,(x/4)th part is filled in 24 hours,
(x/2)th part is filled in 25 hours, (x)th part is filled in 26 hours
So answer is 26 hours.

a) 43 b) 69 c) 52 d) 31
Solution:
Total age of 6 persons is x hours,after two years total age of 6 persons is x+12
Average age of 6 persons is after two years is 43

This happens because population is both a consumer and producer. There are two schools of thought. One which treats population as a resource, and the other as a burden to the society. The truth, in fact, lies somewhere in between. The interplay of factors responsible for population growth and those for development decide the resourcefulness of population.

1) because other resources deplete
2) because population is an ever-increasing phenomenon -Answer
3) because population is seen as a resource

a) 26 B)25 c)5 d)27
Solution: for every hour water in tank in B is doubled,
Let the duration to fill the tank B is x hours.
x/32 part of water in tank of B is filled in 21 hours,
Next hour it is doubled so,
2*(x/32) part i.e (x/16) part is filled in 22 hours,
Similarly (x/8)th part in 23 hours,(x/4)th part is filled in 24 hours,
(x/2)th part is filled in 25 hours, (x)th part is filled in 26 hours
So answer is 26 hours.

a) 43 b) 69 c) 52 d) 31
Solution:
Total age of 6 persons is x hours,after two years total age of 6 persons is x+12
Average age of 6 persons is after two years is 43
