1. Ans. C
2. Ans. A
3. Ans. B
4. Ans. A
5. Ans. A
6. Ans. E
7. Ans. B
8. Ans. D
9. Ans. A
10. Ans. E
11. Ans. D

Detailed Solutions:
1. Sol.
Let the weight of E be x kg
weight of A =2.25 x kg
weight of B =1.125 x kg
weight of C =0.25 x kg
weight of D =0.5 x kg
weight of E = x kg
Now the increasing order of weights is,
C < D < E < B < A
Lightest in weight = C

2. Sol. Let the weight of E be x kg
weight of A =2.25 x kg
weight of B =1.125 x kg
weight of C =0.25 x kg
weight of D =0.5 x kg
weight of E = x kg
Now the increasing order of weights is,
C < D < E < B < A
E is lighter than A,B

3. Sol. Let the weight of E be x kg
weight of A =2.25 x kg
weight of B =1.125 x kg
weight of C =0.25 x kg
weight of D =0.5 x kg
weight of E = x kg
Now the increasing order of weights is,
C < D < E < B < A
E is heavier than C, D

4. Sol. (i) A weighs 2 B
(ii) B weighs 4.5 C
(iii) C weighs 0.5 D
(iv) D weighs 0.5 E
(v) A > E > C
D weights 0.5 E and B weights 4.5 (0.5D) ---> 2.25 D ----> Therefore , B > D
Also B > E because B weights 2.25 (0.5E) ----> 1.125 E
Now concluding all the five statements A > B > E > D > C<d<e<b
</d<e<b

5. Sol. Let the weight of E be x kg weight of A =2.25 x kg
weight of B =1.125 x kg
weight of C =0.25 x kg
weight of D =0.5 x kg
weight of E = x kg
Now the increasing order of weights is,
C < D < E < B < A
Decreasing order of weights is A > B > E > D > C

6. Sol. Let the weight of E be x kg weight of A =2.25 x kg
weight of B =1.125 x kg
weight of C =0.25 x kg
weight of D =0.5 x kg
weight of E = x kg
Now the increasing order of weights is,
C < D < E < B < A
(v) statement is not required

7. Sol. Statements: A >B > D = K
Conclusion:
I. A = K false
II. B > K True

8. Sol. Statements: M < N > R < T
Conclusions:
I. M > R False
II. T = R False

9. Sol. Statements: K < J < M > N
Conclusions:
I. M > J True
II. K > N False

10. Sol. Statements: J < K = L > P
Conclusions:
I. P < K True
II. J < L True

11. Sol. Statements: A > B < C, D < E
Conclusions:
I. C = A False
II. C > A False
