Now in each of hte following questions assuming the given statements to be true, find which of the four conclusion I, II, II and IV. given below them is/are definitely trueand given your answer accordingly.
Statements:
Statements :
`B(c)T,T**R, R%F,F`@K
Conclusions:
`I. B%R`
II.`F**T`
III. `R%K`
IV. `K**T`

Options

A. None is true
B. Only I is true
C. Only III is true
D. Only IV is true

Answer

D

Explanation

B©T`impliesB geT`
`T**RimpliesTltR`
`R%FimpliesR gtF`
F@`KimpliesF=K`
Therefore, `B ge T lt R gt F=K`
Conclusions
I. `B%RimpliesV gt R:` Not True
II. `F**TimpliesF lt T: ` Not True
III. `R%KimpliesR gtK:` True
IV. `K**TimpliesK lt T:` Not true
So only conclusion III is true.
