Question

In the following questions the symbols *,*=,@ are used with the following meanings :
'A*B' means 'A is greater than B';
'A*B' means 'A is either greater than or equal to B';
'A=B' means 'A is equal to B';
'A@B' means 'A is smaller than B';
'A@B' means 'A is either smaller than or equal to B';
Now, in each of the following questions assuming given statements to be true find which of the two conclusions I and II given below them is/are/ definitely true ?
Give answer as ?
(a) if only conclusion I is true;
(b) if only conclusion II is true;
(c) if either I or II is true;
(d) if neither I nor II is true and
(e) if both I and II are true
Statements : M = T, T@Z, Z*M
Conclusion : I. Z*M
II. Z =M

Answer 1

Given statements : M = T, T<Z, Z.M
Now to verify conclusions I and II we need to find a relation between Z and M
Z>T, T = M
⇒⇒ Z>M or Z=M
i.e., Z*M or Z=M
So, either I or II follows
