A, E, F, and G ran a race.
A said “I did not finish 1st /4th
E said “I did not finish 4th”
F said “I finished 1st”
G said “I finished 4th”
If there were no ties and exactly 3 children told the truth, when who finishes 4th?
Read Solution (Total 9)
-
- It is told that exacly 3 children say truth and one of them has lied. So, there are 4 cases possible:-
Case 1:A lied i.e. G says truth and he finished 4th
Case 2:E lied again G says truth so he is 4th
Case 3:F lied i.e. same as above G says truth so he must be 4th
Case 4: G lied i.e. he did not finished 4th. Now other 3 must be saying truth. so A is not 4th , E is also not 4th and F says he is 1st so he is not 4th..This contradicts the assumption that G lied and others said truth since one of them must be 4th. So, this case is not possible.
Therefore, according to first 3 cases, G must be 4th. - 10 years agoHelpfull: Yes(16) No(0)
- G finished the 4th........
Bcoz A and E told not finish 4th, same to F also not in 4th.
so, we will sure G's Statement is True... - 10 years agoHelpfull: Yes(15) No(1)
- ans G...bcz the one who finished last they wiil not lie..
jst simply logic..(:)

- G
assuming individually as one lied once. then it is clear - 10 years agoHelpfull: Yes(2) No(3)
- G finished the 4th........
the reason is no one will lie that he has not completed the race ........taking that into consideration
A and E is not lying ......then among F and G,, F is the one speaking the lie.... - 10 years agoHelpfull: Yes(2) No(2)
- Ans : G
Hit and trial is used here.
if A is lying then A must be 1st or 4th but F and G are not lying so A cannot be either 1st or 4th. Hence A is not lying
if E is lying : he must have ended as 4th but again G is saying the truth that he ended 4th. hence not possible
if F is lying then he must ve ended 2 or 3rd. this is a possible condition - 9 years agoHelpfull: Yes(1) No(0)
- take the case individually, G is the correct ans
- 8 years agoHelpfull: Yes(0) No(0)
- G will finishes 4th
- 8 years agoHelpfull: Yes(0) No(0)
- possibility more belongs to g got 4th place
- 7 years agoHelpfull: Yes(0) No(0)
