Make a valid conclusion in the situation.
If cost price > selling price, then the transaction suffers loss.
Cost price = $255 and selling price = $230.

The correct answer is: Hence we can conclude that the transaction suffers loss.

Hint:
Law of Detachment states that if p  q is true and it is given that p is true then we can conclude that q is also true. Here, the statement is termed as Hypothesis and the statement q is termed as conclusion.
Solution
Consider the statement into two separate statements
p: Cost price > Selling price
q: The transaction suffers loss
So we can write the given statement “If cost price > selling price, then the transaction suffers loss” as:
p q
We are given
Cost price = $255 and Selling price = $230
Here, Cost price > Selling price so we can say that the p statement is true and hence we can conclude that the q statement is also true i .e the transaction suffers loss.
Final Answer:
Hence we can conclude that the transaction suffers loss.
