In each question, three statements showing relation-ships have been given, which are followed by two conclusions / & II. Assuming that the given statements are true, find out which conclusion (s) is/are definitely true.
Give answer (a) : if only conclusion I is true.
Give answer (b): if only conclusion II is true.
Give answer (c) :if either conclusion I or conclusion II is true. Give answer (d): if neither conclusion I nor conclusion II is true.
Give answer (e) : if both conclusions I and II are true.
Statement :M`star`L, L$K, K@R
Conclusion: I. M`star` R II. M@R

Options

A. if only conclusion I is true.
B. if only conclusion II is true.
C. if either conclusion I or conclusion II is true.
D. if neither conclusion I nor conclusion II is true.

Answer

C

Explanation

According to the given informations,
A @ B `implies A lt B " "` A # B `implies A le B`,
A $ B `implies A gt B , " " A star B implies A ge B`
A © B `implies A cancelgt` and `A cancellt` A = B
According to the question
`M ge L ... (i) " " L gt K` ....(ii) `K lt R` ... (iii)
I. Relation between M and R
From (i) , (ii) and (iii) we get
`implies` no definite conclusions regarding M and R .
But conclusion I i.e., `M ge R` and conclusion II i.e., `M lt R` are complementary pair.
Therefore , either conclusion I or II is true .
