have a logical reason for being. However, there are no serious taboos
attached to them. Individuals may have an array of sensitivities based
on their personal beliefs. If you do offend someone inadvertently, a
sincere apology will usually go a long way toward making amends. The one
sensitivity that almost all Americans have is about slights to their
country. Either complaining about the US or expressing an attitude that
your culture is superior can cause Americans to take offence. Americans
do possess a great deal of culture arrogance, and think that their way
is the only right way. They think that the US is the best place on
earth, otherwise why would everybody by trying to get here? Whether you
agree or not, remember that you are a guest in the US and it would be
rude for a guest to insult his host

Passage – II
Population is one resource that never depletes and is a living
development parameter. But it is at times interpreted as a hindering
factor for development. 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?
1) because population is the creator and at the same time it is also the user -Answer
2) because a less number of people are engaged in production and a large number of people are dependent on it
3) because population is not always a producer but it is always a consumer
4) when the growth of population is checked it is a resource and when it increases rapidly it is burden to the society
5) None of these
22. The resourcefulness of population can be decided by
(i) skilled manpower (ii) scale of development (iii) population control measures (iv) scale of population growth
1) All of the above
2) Only (i), (ii) and (iii)
3) Only (i) and (iii) -Answer

1. There are two water tanks A and B, A is much smaller than B. While
water fills at the rate of 1 liter every hour in A, it gets filled up
like, 10, 20, 40, 80, 160 in tank B. (At the end of first hour, B has 10

filled of the 21 hours, what is total duration of hours required to fill
it completely?
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.

years their average age will be 43 and seventh person joined with them.
Hence the current average age has become 45.Find the age of seventh
person?
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
So (x+12)/6=43,then solve x,
After 7th person is added then (x+7th person age)/7=45
So we will get 7th person age easily
