1) u hav fifteen boxes in kitchen and ur mom asked u to make foos for 1 month, wht will u do to make food fast (thn concept of sorting came)
i said i will put name tag on boxes and thn sort thm in ascending order or i can put thm in order of color shade firstly lightest and thn little darker and soon but tht can create confusion so first is better way
2)u hav 1000 names in unorder manner and i asked u to pick any name of my choice randomly and thn giv me complete info of tht person so wht ds will u use
i said firstly i will sort thm thn i will use hashing/btrees as thy r faster in decreasing search domain,
thy asked wich sort will u use
i said radix as good for strings , he asked if one more name increase or decrease i said radix sort take linear time so doesnot affect much on time
he said if names r vary in length like one is venkateshraman other is raj i said sort from 3rd last letter or use padding.

Passage - I
Americans have a variety of superstitions like walking under a ladder, a black cat crossing your path and the number 13, none of which seem to 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
15. Which of the following can be presumed about Americans regarding superstition?
1) It is a cultural custom for them to believe in superstitions.
2) They can satisfy you by placing arguments about the validity of superstitions.
3) Americans cannot justify their adherence to superstitions.
4) Americans are highly superstitious people.
5) None of these

16. If you offend an American inadvertently, a sincere apology will
1) take a long time to repair the damage.
2) not necessarily by enough to amend it.

1) mad rush of people from other countries to America
2) the best facilities available there
3) their culture and custom which they feel is the best in the world
4) the economic superiority of America
5) None of these

19. What is the antonym of the word inadvertently as given in bold in the passage?
1) intentionally
2) occasionally
3) unwittingly
4) avowedly
5) adroitly

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
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
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)
4) Only (ii) and (iv)
5) None of these

23.Which of the following is true in context of the passage?
1) It is not necessary that the population always grows.
2) Population is burdensome.
3) Most of the natural resources are exhaustible.
4) Population is a big consumer and a meager producer.
5) None of these

24.What will be the synonym of the word depletes as given in bold in the passage?
1) disappears
2) sustains
3) worsens
4) evades
5) reduces

25. – 65 x39 + 335 =?
1) – 849225
