Solutions:

Q1-Q2:
P > Q > U(63kg) > R > T(50kg) > S
Q1. A, Q2. D

Q3. A
Given statement:
S > M >= D > H <= R <= T < W
Thus, S > H is true. Hence I is true. Again, H < W or W > H is true. Hence II is true.
R < W is true. Hence III is also true. But we can’t compare M and T. Hence IV is not true. Hence only I, II and III are true.

Q4. B
Given statement:
M > U > L <= N  …(i)
L >= Y > A  …(ii)
Combining (i) and (ii), we get
M > U > L >= Y > A and A < Y <= L <= N
Thus, Y <= N is true.
Hence, Y < N may be true.
And Y = N may be true.
So, conclusion I and III make a complementary pair.
Thus, either I or III is true.
Again, we can’t compare M and N. Hence II is not true.
But M > A is true. Hence IV is true. Hence only IV and either I or III are true.

Q5. D
S14. Ans.(d)
Sol. J >= A > D = E   …(i)
L < A < M   …(ii)
Combining (i) and (ii), we get
M > A > D = E   …(iii)
J >= A < M   …(iv)
J >= A > L   …(v)
L < A > D   …(vi)
Thus, from (iv), we can’t compare J and M. Hence I is not true.
From (v), J > L is true. Hence II is true.
Again, from (vi), we can’t compare D and L. Hence III is not true.
Now, from (iii), M > E or E < M is true. Hence IV is true.
Thus, only II and IV are true.
