(e) None of these
Solution for 4th and 5th questions.
In terms of height we have : Gopal < Ashok, Kunal < Gopal, Navin <
Kunal,
Navin < Jayesh, Jayesh < Ashok.
So, the sequence becomes: Navin < Kunal < Gopal < Jayesh < Ashok.
Answer for 4th question is (b), Clearly, Ashok is tallest.
Answer for 5th question is (c), Clearly, statement C is not
necessary.
6.B is twice as old as A but twice younger than F.
C is half the age of A but twice the age of D.
Which two persons from the pair of oldest and youngest?
(a) F and A (b) F and D (c) B and F
(d) F and C (e) None of these
Answer is (b)
Let's A's age be x, then B's age is 2x. B is twice younger than F i,e
F
is twice older than B. So, F's age is 4x. C is half the age of A i,e
C's
age is x/2. C is twice the age of D i,e D is half the age of C i,e
D's
age is x/4. So, the descending order of ages is F, B, A, C, D.
Clearly, F is the oldest and is the youngest.
