‘P $ Q’ means P is neither smaller than nor equal to Q

‘P @ Q’ means ‘P is not greater than Q

‘P * Q’ means ‘P is neither greater than nor smaller than Q

‘P © Q’ means ‘P is neither greater than nor equal to Q

‘P # Q’ means ‘P is not smaller than Q


Now in each of the following questions assuming the given Statements to be true, find which of the Conclusions I, II, III and IV given below then is/are definitely true.

Statements:

 Z# H, B © H, K$ B

III. K $ H                        

IV. Z $ B

Options:
A) Only I is true
B) Only II is true
C) Only III is true
D) Only IV is true
E) None of these
Solution:
Sol;- (d)

$ = P > Q;    @ = P ≤ Q;

*  = P = Q    © = P < Q

# = P ≥ Q

 

Statements

Z ≥ H, B < H, K > B

∴ Z ≥ H>B<K
