Question

It is given that cost of A = cost of B and cost of B = cost of C, then cost of A = cost of C. Which of the following axioms can be applied in the above case?

• A. If equals are added to equals, the wholes are equal
• B. Things which are equal to the same things are equal to one another
• C. If equals are subtracted from equals, the remainders are also equal
• D. None of the above

Answer 1

The correct option is B Things which are equal to the same things are equal to one another

The axiom "Things which are equal to the same things are equal to one another" could be applied here.

For example, in the case above the cost of A and cost of C are equal to the cost of B. Now, by applying the above axiom it can be inferred that cost of A = cost of C.
