1. Who is the youngest?
A.Deepti
B.Rajan
C.Lata

Solution:
(1-5): Let Mahima’s age = x.
Then Anita’s age = 2x,
Rajan’sage =x/2;
Deepti’s age = 4x;
Lata’s age =x/4.
So, the descending order of ages is :Deepti> Anita >Mahima>Rajan>Lata.
Lata is the youngest

B.Lata
C.Anita
D.None of these
Solution:

B.5 years
C.7 years
D.14 years
Solution:

(v) D is elder to A but is shortest in the group.
6. Who among the following is the eldest?
A.A
B.B
C.C
D.None of these
Solution:
In terms of age, we have : E < B, C < A, A < E, A < D. So we have : C < A < E < B, A < D.
In terms of height, we have : B < C, D < C, E< C, D < A. So we have : B,D,E < C , D < A
6. (d): Either B or D is the eldest.

C.All are correct
D.All are incorrect
Solution:
B is shorter than C. So, B is not the tallest. Thus (i) is correct.
B and E are shorter than C. So, it cannot be concluded that B is shorter to E. Thus, (ii) is incorrect.
A single definite order of heights cannot be obtained from the given information. So, (iii) is incorrect.
9. If F, another friend, is taller than C, how many of them will be between F and E according to their height?
A.None
B.One
C.Two
D.None of these
Solution:
Since no definite order of height can be obtained, so it cannot be determined for sure how many persons lie between F and E.
