P @ Q means P is greater than Q.
P `underline"@"` Q means P is either greater than or equal to Q.
P = Q means P is equal to Q.
P © Q means P is smaller than Q.
P `underline"©"` Q means P is either smaller than or equal to Q.
Statements: `I underline"©" J, K = J underline"©" L, H underline"@" J`
Conclusions: I. J = L II. ` I underline"@" H`

Options

A. If only I is true
B. if only conclusion II is true
C. if either conclusion I or II is true
D. if either I nor II is true

Answer

B

Explanation

Statements: `I le J, K = J le L, H ge J`
Conclusions: I. J = L II. `I le H`
There are no equalities involving L in the given statements, so there can.t be any equality involving L in any conclusion (Tip 7): So, I is wrong. For II, `I le J` and `H ge J` are relevant. Combining them we get `I le I le H` which gives `I le H.
