P `o+` Q means P is greater than Q.
P `underlinecancel("©")` 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 `underlinecancel("@")` means P is either smaller than or equal to Q.
Statements: S `underlinecancel("@")` F, K @ S, B = K, R `o+` B
Conclusions: I. F `o+` K II. K @ R

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 both are true

Answer

D

Explanation

Statements: `S le F, K lt S, B = K, R gt B`
Conclusions: I. `F gt K` II. `K lt R`
From `S le F` and `K lt S` we get `K lt S le F` to get `K lt F`. So, I follows. Now, From B = K and `R gt B`, II follows.
