The average age of 27 children and their teacher's age are 23 years. If the teacher's age is excluded, the average reduces by 1. What is the teacher's age?

Statement: F ≥ I ≥ S ≥ H ≥ Y

Conclusion: I. H ≤ F                          II. Y ≤ I

Statements:

A < R ≤ Y = F; U > L = T; A < L = P > E

Conclusions:

I).  U > E

II).  T > Y

Statements: D > E ≥ I > G; L = F < H ≤ G; L > J

Conclusions:

I. E > J

II. L ≤ D

III. I ≥ F

Which of the following expressions will be true if the expression Q ≥ M = R > F = E ≤ X is definitely true?

Statement: A > B = C < D > E; F ≤ H < I; E > G > I

Conclusions:

I. D > F

II. F < G

III. B < G

Which of the following expressions will be true if the expression ‘L ≥ M < N = O’ is definitely true?

Statements: L ≥ O = J ≥ I ≤ V; C = T ≤ J

Conclusion: I. C < L II. C = L

Statements: J @ K, K $ L, L & M, M % N

Conclusions: I. K @ M                  II. N & J

Statement:  P ≤ W < O = D ≥ G > T

Conclusions:

I.  P ≤ T

II. W < D
