'A' is equal to 'B' and 'B' is equal to 'C', then what can be concluded, choose the most appropriate alternative as given below.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → A is equal to C
Equality is transitive: if A = B and B = C, then A and C are both equal to the same B, so A = C.
Why the other options are incorrect
Option (2) A+B is equal to C — Incorrect. All three are equal, so A + B is twice C, not C (unless all are zero).
Option (3) A is not equal to B — Incorrect. It contradicts the first given fact, A = B.
Option (4) B is not equal to C — Incorrect. It contradicts the second given fact, B = C.
