AGES R 73 &37

POSn :b d c a e

Ans 1: 73 n 37

Ans 2: Since A n B have lied A has to be in the last position and c should not be in the third position.... Since C D n E have told the truth E must be in the fourth position (coz of C's statement) which leaves C to be in either first or second position. C cannot be in the first position coz of D's statement. Hence C is in the second position which leaves d the third position......

Therefore the order is B C D E A

my answer for part a is

73&37

second part has only one answer i.e B D E A C WHERE B IS THE FIRST

1.)73 & 37

2.)BCEAD

consider B in 1st place.....

1.D says B is in 1st place is true. so D cant b in 2nd place(silver medal!)

2. E says D is not the first... is true. so E cant b in 2nd place

3. A says i'm not last is true if A is in 2nd place. hence A cant b in 2nd place

4. So C has to b in 2nd place.

now B C in first n second place resp

5. E cant b behind A as C is false.

6. E shud b before A. and since E is true A cant b last.

So _ _ _ will b

> A _ _ which wont b right ...acc to (5).

>_ _ A wont b right .....acc to (6)

>_ A _ will b right.

As E is before A it will be E A _.....ie. EAD

hence

B C E A D
