[2008] DI and VA/RC Question a Day by Arun Sharma's Mindworkzz

[implex]

My previous solution was in correct

lets do this again
analyse A B C and F they have no match at any position
so one of them has zero correct, other 1 , other 2 and the fouth has to have (7-1-2)= 4 correct

now it is easy to see that C is the one with 4 correct
this further means D and E have one as 3 correct and other as 5 correct

which makes it obvious that E has 5 correct and D has 3 correct

SO order is 7 6 3 1 2 4 5

so solution is

1 d 2 c 3) a 4) b 5) a

[masoom]

what i have done is...

since at least one bookie will get the bet right..

first i found out the horses which cant take a position

its like :

position Horses not eligible

1 H2,H3,H4

2 H1,H4,H3

3 H1,H4,H5

4 H5, H2, H7

5 H6

6 H1,H3,H4

7 H6, H1, H4,H3

now in the given table H4 is repeated max times at position 6...

so a hint is there that it might be in position 6...

to give variable answers...

then i checked by putting options..

H5 was not satisfying...

and then by 4-5 iterations..

the order 7 6 3 1 2 4 5 satsfied all teh criteria...

found it after many hardships any ways first of all thanks to PG and arun sharma

sequence is H6, H2, H3, H1, H5 , H4 , H7
so the answers are

1) Option c
2) Option a
3) Option b
4) Option c
5) Option a

lets c what is the take of others

Kindly explain.
Thanks in advance..

sequence is H7, H6, H3, H1, H2 , H4 , H5

so two sequences is H6, H2, H3, H1, H5 , H4 , H7
&
sequence is H7, H6, H3, H1, H2 , H4 , H5

finally i think
sequence is

Rank 1 H7 or H6
Rank 2 H6 or H2
Rank 3 H3
Rank 4 H1
Rank 5 H2 or H5
Rank 6 H4
Rank 7 H5 or H7

so the answers after modification are

1) Option e
2) Option e
3) Option e
4) Option e
5) Option a

the combination in bold is wrong as coz if thats the sequence , then A and E end up having the same number of correct bets which is not the case

Hey everyone,
It seems, in the newsletter, just below Q1 the correct order has been given.

[Fuzon]

my approach, i tried with the highest possible number of bets , which can be 5 .
Also if we have a look at the mismatch in the bets , D and E can appear to be the ones which can have 5 correct bets , further drilling shows E is the one with 5 bets right , now i seriously did it by trial and error and underwent a lot of pain for the comination as out of 7 ranks 5 ranks can be chosen in 7c5 ways lolzzzzzz

one combination that hit was 7 6 3 1 2 4 5

Answers
1) d
2) c
3) a
4) b
5) a

Maybe your answer is correct.... but i would not agree with your process. There is a much more strucured way to solve this question.... Pls remember, if a question of this difficulty and length does enter into the CAT, it will lead to a riot.

So all we at pagalguy are trying to give you is a learning opportunity, so that whatever you face in the CAT is easier than what you have seen.

God Bless!! The horse race has begun!! (sic!)

[ArunSharma@Mindworkzz]

The process is always more important than the end product.....perhaps the most imp thing for cat prep....

if you hit on the correct process you will not need to check for answers to any question you solve...

Hey I noticed that too... but whats the point? we should be more intrested in methods or approches to solving the problem.

Nice to see you, Mr. Sharma, But I think my solution is good and has a neat backing to it
