*DI Marathon for CAT 2007*

[nishant_rungta]

Here are my answers...

1) its option c England and Ireland.. Thats pretty obvious i believe

2) its option b 1..
See, Because India and NZ obtain a total score of 0 and they play 5 matches they must have won 1 match, tied 1 match and lost 3 matches.. this way they gain 3 points from a win and a tie and lose 3 points on 3 losses.. That makes it 0.. hence they win 1 match each...

3) its option a -2... Cuz to be a second runner up the team must have lost both the matches so that would make its score -2. The first runner up must ve won 1 match and lost 1 so its score is 1. But here again i have a doubt cuz wat if two teams in the finals lose one match each n draw one match... their score would be 0 and they wud be deemed as Second runners up.. Is it possible.. In that case the answer must be CANNOT BE DETERMINED!!! Plz clear my inhibitions..

4) Very much puzzled by the question.. cannot comprehend how to approach this one... does it mean all the 6 teams or only 3 teams that qualify and also shud it include the points of the 1st round as well???

Hence answer should be 2 i.e., option c

Since only teams with better averages advance into the final stage
result will be the same in the two cases u mentioned

after that i am stuck.
"In the super six round, the total points earned by all the teams are 50."

This statement is very ambiguous.If it's means total points obtained in super6 only
(with out taking points from first round) then it's not feasible.Beause in sup6 total no matches r 15.So max total points possible is 30.

if it's meant total from first and sup6 then also a prob.
after sup6 total points =50.
total after final =58.
In three matches we cannt obtain 8 points.

plz throw some light here..

Agree that the highlighted part was dicey.
K. I'll rephrase it.
"After supersix round, the total points earned by the teams(that played in the supersix round) is 50."
Now try again.

Can you elucidate?
AFAIK no assumptions are required.
Will clarify your answers once you explain your assumptions and the approach.

divided the total by avg. pts to find the number of matches played by each team...
Comes out to...

Teams Ban / Ind / Ken / Nz / Eng / SA / Aus / Ire / Pak / SL / WI / Zim
No. of matches 12 / 6 / 10 / 6 / 10 / 6 / 6 / 12 / 6 / 10 / 6 / 12

thus concluded that Ban,Ken & Eng from pool A and Ire,Sl and Zim from pool B went into super sixes out of which Ban,Ire and Zim played in the finals.

from this Qs 1 & 2 can be easily answered..

Q3> Now it was given that the winner won both its matches in the final round.So the second runner up either gets a -2 by losing both the matches or theres a tie between the 2nd and 1st runners up and both get 0. Now, looking at the data given Ban are the winner since they have the highest avg.so now looking at Ire and Zim...i found that though Zim made it to the final even though their points & avg. are less then Eng which did not make it to the finals...so assumed that the lost both their matched in the finals and hence they were the second runner up with -2 points.

Q4> now as we had concluded that Ban had won both there matches in the finals they got 4 points in the final two matches...therefore their avg before final is (14-4)/(12-2)=1

for Ire they won a match and lost another in the finals...therefore net is -1+2= +1...therefore their avg before final is (13-1)/(12-2)=1.2..which comes out to be the highest avg...since Zim if calc on similar lines will have a lower avg

i m solving these Qs from office...so i dont get much time to do them...i try to find some time between work...anyways...waiting 4 the solutions and explanation

[Fabio capello]

@ anybody ....can you please post the answers and next set of ques pls

[doomsayer]

1. Which 2 teams do not play against each other in the finals?
a) Ban, Ire b)Ban,Zim c)Eng, Ire d)Ire, Zim

2.Find the number of matches won by Ind and Nz in the first round.
a) 0 b) 1 c) 2 d) 3

3. How many points did the second runner up earn in the final round?
a) -2 b) 1 c) 2 d) Cannot be determined

4.After supersix round, the highest average points of any team are
a) 1 b)1.2 c)1.3 d) Cannot be determined

my answers:
1)c
2)c
3)a
4)b

Soln:The table showed in the que is actuaaly score after final results
Here we have to find the no of matche played by each.
No of matches = total point/ avg.


Then we get ban,ire,zim,sl,ken, eng get into super six and ban ,ire,zim play the finals
it's obtained from no of matches played. finalists play 12 matches and sup6 exit teams play 10 matches.
So from here we get the ans of first question.(c)


Then the tot points after sup6 of sup six teams r 50 and their tot points after final is 53.
That means 3 points they get from final.And it's said the winner won 2 of it's matches.
So to get 1 more point, the other match do not end draw

So the out put 3 fin matches r two wins for the winner.And right now we dont knowwho is tne winner of the match between first runner up and second runner up.

Then the winner is decided by the avg.So since the table in question it's directly undrstand Ban is the winner and ire second and zim third.

Then the outcome of first run up and sec run up?
One team got 1 point and the other team lost 2.But we dont know whos who
zim's total score after final is 7.If it's obtain one more point in the final then it's point bef final is 6 in that case it's avg is .6 and it will not qualify for final .That means zim is the team who lost 2 points.

So the ans of 3rd question .(a)

The score of ire after sup 6 is 12.So it's avg is 1.2
So the ans of 4th question (b)

Now the tolal wins of ind and nez.Both got 0 points .It can posiible only if 1w 1d 3f
so the ans of second question(c)
