**Directions for Questions 16 to 20: The passage given below is followed by a set of five questions. Choose the most appropriate answer to each question.**

To summarize the Classic Maya collapse, we can tentatively identify five
strands. I acknowledge, however, that Maya archaeologists still disagree
vigorously among themselves—in part, because the different strands evidently
varied in importance among different parts of the Maya realm; because detailed
archaeological studies are available for only some Maya sites; and because it
remains puzzling why most of the Maya heartland remained nearly empty of
population and failed to recover after the collapse and after re-growth of
forests.

With those caveats, it appears to me that one strand consisted of
population growth outstripping available resources: a dilemma similar to the
one foreseen by Thomas Malthus in 1798 and being played out today in Rwanda
(Chapter 10), Haiti (Chapter 11), and elsewhere. As the archaeologist David
Webster succinctly puts it, “Too many farmers grew too many crops on too much
of the landscape.” Compounding that mismatch between population and resources
was the second strand: the effects of deforestation and hillside erosion, which
caused a decrease in the amount of useable farmland at a time when more rather
than less farmland was needed, and possibly exacerbated by an anthropogenic
drought resulting from deforestation, by soil nutrient depletion and other soil
problems, and by the struggle to prevent bracken ferns from overrunning the
fields.

The third strand consisted of increased fighting, as more and more
people fought over fewer resources. Maya warfare, already endemic, peaked just
before the collapse. That is not surprising when one reflects that at least
5,000,000 people, perhaps many more, were crammed into an area smaller than the
state of Colorado (104,000 square miles). That warfare would have decreased
further the amount of land available for agriculture, by creating no-man’s
lands between principalities where it was now unsafe to farm. Bringing matters
to a head was the strand of climate change. The drought at the time of the
Classic collapse was not the first drought that the Maya had lived through, but
it was the most severe. At the time of previous droughts, there were still
uninhabited parts of the Maya landscape, and people at a site affected by
drought could save themselves by moving to another site. However, by the time of
the Classic collapse the landscape was now full, there was no useful unoccupied
land in the vicinity on which to begin anew, and the whole population could not
be accommodated in the few areas that continued to have reliable water
supplies.

As our fifth strand, we have to wonder why the kings and nobles failed
to recognize and solve these seemingly obvious problems undermining their
society. Their attention was evidently focused on their short-term concerns of
enriching themselves, waging wars, erecting monuments, competing with each
other, and extracting enough food from the peasants to support all those
activities. Like most leaders throughout human history, the Maya kings and
nobles did not heed long-term problems, insofar as they perceived them. We shall
return to this theme in Chapter 14.

Finally, while we still have some other past societies to consider in
this book before we switch our attention to the modern world, we must already
be struck by some parallels between the Maya and the past societies discussed
in Chapters 2-4. As on Easter Island, Mangareva, and among the Anasazi, Maya
environmental and population problems led to increasing warfare and civil
strife. As on Easter Island and at Chaco Canyon, Maya peak population numbers
were followed swiftly by political and social collapse. Paralleling the
eventual extension of agriculture from Easter Island’s coastal lowlands to its
uplands, and from the Mimbres floodplain to the hills, Copan’s inhabitants also
expanded from the floodplain to the more fragile hill slopes, leaving them with
a larger population to feed when the agricultural boom in the hills went bust.
Like Easter Island chiefs erecting ever larger statues, eventually crowned by
pukao, and like Anasazi elite treating themselves to necklaces of 2,000
turquoise beads, Maya kings sought to outdo each other with more and more
impressive temples, covered with thicker and thicker plaster— reminiscent in
turn of the extravagant conspicuous consumption by modern American CEOs. The
passivity of Easter chiefs and Maya kings in the face of the real big threats
to their societies completes our list of disquieting parallels.

x+y+z

----- = 6800

3

x>=6400

6400 + y + z = 20400

y + z = 14000

to get the greatest of y and z, lets assume y = 6400

so, z = 7600

so ANS is 7600

----- = 6800

3

x>=6400

6400 + y + z = 20400

y + z = 14000

to get the greatest of y and z, lets assume y = 6400

so, z = 7600

so ANS is 7600

14.Ans.Rs.34000

per year=700*12=8400

then for 5 years=8400*5=42000

for maintanace rs 100 for 5 year=6000

=42000-6000-2000

=34000

then for 5 years=8400*5=42000

for maintanace rs 100 for 5 year=6000

=42000-6000-2000

=34000

15.Ans.9000

48000 / 9600 = 5

5 * 7800 = 39000

therefore 48000 - 39000 = 9000

16. Ans.3/4

Number of weeks in a year = 52

Total orders in a year = 52/2 = 26 (Because every other weeks means,
alternate)

so after 28 weeks no. of orders should be 28/2 = 14

Originally completed orders in 28 weeks = 14 - 6 = 8 orders (Because 6
orders behind)

next 24 (52- 28) weeks, orders needed to collect = 26 - 8 = 18

So, required proportion for remaining weeks = 18/24 = 3/4

17. Ans.14000

It is given for every 800 cheques 100 are error

so (800-100)=700 error free

total 16000 cheques

so dividing them into 800 in each we get (16000/800)=20

so 20 sets of cheques (each 800) where each set has 700 error free

so 20*700=14000 is the answer

18. Ans.Rs.87

A computing centre normally spends Rs.1440/- a month for tapes and 3/4
of this is for heavy duty tapes.

Amt spent on HD tapes = 1440*3/4 = Rs 1080.

Amt saved on HD tapes = 1080*2/30 = Rs 72.

Amt spent on regular tapes = Rs 360

amt saved on regular tapes = 360*1/24 = Rs 15

Total amt saved = 72+15 = Rs 87

Amt spent on HD tapes = 1440*3/4 = Rs 1080.

Amt saved on HD tapes = 1080*2/30 = Rs 72.

Amt spent on regular tapes = Rs 360

amt saved on regular tapes = 360*1/24 = Rs 15

Total amt saved = 72+15 = Rs 87

19. Ans. 6"

sum of dimensions now = 48+30+52 = 130'

Increased sum of dimensions = 156'

increased smallest side = 156*30/130 = 36 "

increase in smallest side = 36-30= 6"

Increased sum of dimensions = 156'

increased smallest side = 156*30/130 = 36 "

increase in smallest side = 36-30= 6"

20. Ans.33%

If there are total 100 employees , then 35 are men and 65 are women

men who attended picnic = 35*0.2 =7

women who attended picnic = 65*0.4 = 26

total persons out of 100 who attended picnic = 7+26 =33

so 33% of all the employees went to the picnic.

men who attended picnic = 35*0.2 =7

women who attended picnic = 65*0.4 = 26

total persons out of 100 who attended picnic = 7+26 =33

so 33% of all the employees went to the picnic.

21.Ans. 35000

Let the no. of copies be x.

We know Profit = Selling Price - Cost Price.

Here s.p = Rs. 0.5*x

c.p = Rs. 0.7*x-15000

profit = Rs. 8000

Therefore, 8000 = 0.5x - (0.7x - 15000)

x = 35000

We know Profit = Selling Price - Cost Price.

Here s.p = Rs. 0.5*x

c.p = Rs. 0.7*x-15000

profit = Rs. 8000

Therefore, 8000 = 0.5x - (0.7x - 15000)

x = 35000

22.Ans. father-73, son-37

My age : 10x+y

Son age : 10y+x

So 10x+y = 10y+x

10x+y-1 = 2(10y+x-1)

x = (19y-1)/8

For y=3 (19y-1) is completely divisible by 8

So x = 7

So my present age : 10*7+3 = 73

Son's age : 10*3+7 = 37

Son age : 10y+x

So 10x+y = 10y+x

10x+y-1 = 2(10y+x-1)

x = (19y-1)/8

For y=3 (19y-1) is completely divisible by 8

So x = 7

So my present age : 10*7+3 = 73

Son's age : 10*3+7 = 37

23. Ans. 8

Weigh 1/3 of the number of balls against another 1/3.

If they are equal, the heavy ball is in the 1/3 that you didn't weigh.

Each weighing eliminates 2/3 of the number of balls.

6561 = 3*8 so you need 8 weighings.

If they are equal, the heavy ball is in the 1/3 that you didn't weigh.

Each weighing eliminates 2/3 of the number of balls.

6561 = 3*8 so you need 8 weighings.

It will arrive at its destination at 3 pm

so it will cross paths with a lorries that leave before 3 pm

ie the ones that leave the destination at 6am, 7am, 8am. 9 am 10 am 11, am 12 noon,

1pm and 2 pm ie 9 lorries and it will arrive just as the 10th one leaves.

so it will cross paths with a lorries that leave before 3 pm

ie the ones that leave the destination at 6am, 7am, 8am. 9 am 10 am 11, am 12 noon,

1pm and 2 pm ie 9 lorries and it will arrive just as the 10th one leaves.

30. Ans: 60 kmph

Suppose Person meets the train everyday at 3 PM at Station A.

Suppose Person meets the train everyday at 3 PM at Station A.

His speed is 12kph.

So normally he reaches 5 km before the meeting point (pt B) at (5/12 hr
= 25 min before) 2:35PM.

But if he is late by 30 min, then he will reach that point (pt B) by
3:05 PM.

Train is traveling at its normal speed so it covers the distance of 5 Km
in 5 min starting from Station A and reaches the meeting point (pt B) at 3:05
PM.

So speed of the train is 5KM/5min = 60 kph.
