Sajeed and Majeed are gambler.they love talking on final team ranking in cricket tournament.LPI cricket tournament is thier favorite.
A total of five team is participating in this year LPI(A,B,C,D,E).before the tournament begins,sajeed and majeed guess the result.
According to sajeed ranking will be A,B,C,D,E where according to majeed thier ranking will be D,A,E,C,B.At the end of tournament it turns out
that sajeed had not predicted even a single rank corectly nor he had predicted correct ordering of any pair of consecutive teams.on the other hand
majeed had predicted ranking of two teams correctly and he had also predicted ordering of two pairs of consecutive teams.
Answer the following quenstion
(a) :Which Team Won LPI tournament this year
1:) A
2:) B
3:) E
4:) None Of These
(b) :Which team was ranked one behind team B
1:)A
2:)C
3:)D
4:)None Of These
Read Solution (Total 12)
-
- sajeed has figured the order and the rankings both wrong.
so ABCDE, ranks are wrong and so are the ordering of pairs.
majeed has figured 2 ranks correctly .
these two should be consecutive, otherwise the other correctly ordered pair would result in a 3rd correct prediction.and the correct ranks should be at either ends. ie top or bottom ranks,otherwise the other correctly ordered pair would result in a 3rd correct prediction.
so either the DA_ _ _ or _ _ _CB is correct.
in top case we can have correct ordering of 2 pairs EC or CB that are displaced by 1 position but both of DACBE, DABEC violates the fact that sajeed is wrong.
in bottom case we have,EDACB and AEDCB . AEDCB is wrong as A can't be in position 1.
so EDACB is the correct answer - 12 years agoHelpfull: Yes(64) No(5)
- E D A C B is the correct order,it satisfies both sajeed and majeed rules...
C&B SATISFIES THE RANKS,DA&CB SATISFIES THE ORDER.
thank you:)
- 12 years agoHelpfull: Yes(13) No(5)
- sorry i did a mistake in previous ans,but now is right
now sajeed had not predicted even a single rank corectly nor he had predicted correct ordering of any pair of consecutive teams,so
A-1,B-2,C-3 D-4 E-5
SO A can not come at 1st place,B can not come at 2nd place and so on
now acc. to majid D-1,A-2,E-3,C-4,B-5(these are the palace,such as d has 1st place)
so we can see that majeed had predicted ranking of two teams correctly and he had also predicted ordering of two pairs of consecutive teams.
so acc to sajid the place of A and C is 1 and 3
but acc to majid A and C is 2 and 4 consecutively
so first two
after pridicting two corectly,all sequence will be change,the new sequence is
E D B A C
1) team E has Won LPI tournament this year(ans)
2)team D was ranked one behind team B (ans)
if any type of query please-2 post:)
(a) :Which Team Won LPI tournament this year
3:) E (ans)
(b) :Which team was ranked one behind team B
3:)D(ans)
- 12 years agoHelpfull: Yes(10) No(37)
- E D B A C HOW IT COMES??IT DOESN'T SATISFY MAJEED RULE NA..NO TWO TEAMS ARE CORRECT,AND NO ORDERING IS SATISFIED IN "D A E C B"
- 12 years agoHelpfull: Yes(2) No(7)
- DABEC bcoz , majeed had predicted ranking of two teams correctly and he had also predicted ordering of two pairs.
- 8 years agoHelpfull: Yes(2) No(4)
- now sajeed had not predicted even a single rank corectly nor he had predicted correct ordering of any pair of consecutive teams,so
A-1,B-2,C-3 D-4 E-5
SO A can not come at 1st place,B can not come at 2nd place and so on
now acc. to majid D-1,A-2,E-3,C-4,B-5(these are the palace,such as d has 1st place)
so we can see that majeed had predicted ranking of two teams correctly and he had also predicted ordering of two pairs of consecutive teams.
so acc to sajid the place of A and C is 1 and 3
but acc to majid A and C is 2 and 4 consecutively
so first two
after pridicting two corectly,all sequence will be change,the new sequence is
A C D B E
so
1). A Won LPI tournament this year
2).D team was ranked one behind team B - 12 years agoHelpfull: Yes(1) No(34)
- Another Solution could be D A B E C. I feel there can be multiple answers to this and hence the answer would be none of these
- 9 years agoHelpfull: Yes(1) No(4)
- sajeed has figured the order and the rankings both wrong.
so ABCDE, ranks are wrong and so are the ordering of pairs.
majeed has figured 2 ranks correctly .
ab correct
abecd - 10 years agoHelpfull: Yes(0) No(4)
- manish BDECA why cant be the answer
- 10 years agoHelpfull: Yes(0) No(5)
- in given question sajeed give prdiction A,B,C,D,E which is wrong positions or wrong pairs
on the other hand Majeed give prediction D,A,E,C,B which have two position as well as two pairs correct
So lets start,
Suppose, According to majeed prediction D,A,E,C,B
we can make 4 pairs i.e (D,A) (A,E) (E,C) (C,B)
now Select any pair for first position, so there are four conditions
1. suppose if (D,A) placed at first position then,
we have to change positions of all three
we have remaining E,C,B so there can made two pairs (E,C) and (C,B)
now we can not put (E,C) at second position because it leads to negotiating majeed prediction (i.e 4 positions are correct D,A,E,C)
So we should put (E,C) at the end.then
(D,A),B,(E,C)
now A,B make there pair so this arrangement is not correct.
2. now the second pair (A,E) should not placed at first position it leads to satisfy sajeed prediction(i.e a placed at its position).
So, this arrangement is also not correct.
3. Now third pair (E,C) can placed at first position then
we have only one pair remaining i.e (D,A) because B is at the end position
so we have to placed to another position
so, we can arrange as
(E,C),B,(D,A)
Now this arrangement follows both sajeed and majeed conditions So it should be one possible arrangement for the problem..
4.Now if we place pair (C,B) at first place it also satisfy sajeed prediction (i.e B at second position)
So there is only one possible arrangement for the ranks according to problem
i.e E,C,B,D,A
So answer of asked questions are:
1. E won LPL this year
2. D was ranked one behind B - 8 years agoHelpfull: Yes(0) No(4)
- DABEC satisfy all the conditions so
Ans)a=4
B=4 - 7 years agoHelpfull: Yes(0) No(1)
- Sajeed had not predicted even a single rank correctly nor he had predicted correct ordering of any pair of consecutive teams, so
A-1,B-2,C-3, D-4, E-5
SO A can not come at 1st place,B can not come at 2nd place and so on.
Now acc. to majeed D-1,A-2,E-3,C-4,B-5 (these are the palace,such as d has 1st place)
So we can see that majeed had predicted ranking of two teams correctly and he had also predicted ordering of two pairs of consecutive teams.
So acc to sajid the place of A and C is 1 and 3, but according to majid A and C is 2 and 4 consecutively.
So first two after predicting two correctly, all sequence will be change,the new sequence is A C D B E. - 7 years agoHelpfull: Yes(0) No(0)
