The cost price of an article is C and the selling price of the same article is S, where Z is the profit or loss percentage. If the CP and SP both are increased by same amount then which of the following is true :
Correct Answer: Z decreases
Explanation:
The profit = SP - CP
If SP and CP both increase at same amount then the profit would be same. As we know profit % (Z) = Actual profit / CP
So if CP increases the profit % (Z) will go down as there is no change in actual profit.
