Directions (1-5): In the following questions the symbols @, +, ©, $, ∆ and ? are used with the following meaning:
P ∆ Q means P is not equal to Q.
P @ Q means P is greater than Q.
P + Q means P is smaller than Q.
P © Q means P is either greater than or equal to Q.
P $ Q means P is either smaller than or equal to Q.
P ? Q means P is equal to Q.
