A statement is given followed by two conclusions. Find which conclusion is TRUE based on the given statement. Statement: C < A ≤ T = D ≤ O; G ≤ D < S; T ≥ A Conclusions: I: T ≤ O II: D < T
- (a)Both I and II
- (b)Neither I nor II
- (c)Only I
- (d)Only II
Answer
Why
Correct — C.
Rule: along a chain with every sign facing one way, the result is < if any link is strict, ≤ if none is, and = only if every link is =.
I: T = D and D ≤ O, so T ≤ O. True.
II: the statement gives T = D, so D equals T and cannot be less than it. False.
Only I holds → option (c).
Why the others are wrong
- (a)Both I and II — Both I and II accepts D < T, but T = D is stated outright. Two equal letters can never have one strictly smaller than the other.
- (b)Neither I nor II — Neither I nor II rejects I, yet T = D ≤ O gives T ≤ O directly. An equals sign passes the ≤ through unchanged.
- (d)Only II — Only II reverses the result. II is the false one, since T = D, while I follows from T = D ≤ O.
Concept
An inequality item gives a chain of signs and asks which relations are definitely true. Join the two letters of a conclusion through the chain, then combine the signs you pass.
Here T = D ≤ O links T to O through one = and one ≤, which gives T ≤ O. Conclusion II is settled by a single link: T = D rules out D < T.
Much of the statement never matters here. C < A and G ≤ D < S add letters but no new link between T, D and O. T ≥ A repeats A ≤ T from the first chain.
Key facts
- An = followed by ≤ combines to ≤: T = D ≤ O gives T ≤ O.
- If two letters are joined by =, neither < nor > can hold between them.
- T ≥ A says the same as A ≤ T.

Common traps
- Rejecting T ≤ O because T and O might be equal, though ≤ already allows equality
- Reading the = in T = D as ≤ and treating D < T as possible
