Define x:
Let the cost price of 1 article be x
⇒ The cost price of 24 articles = 24x
Find the selling price of 1 article
15 articles = 24x
1 article = 24 ÷ 15 = 1.6x
Find the gain:
Gain = Selling Price - Cost Price
Gain = 1.6x - x = 0.6x
Find the gain percentage:
Gain Percentage = (Gain / Cost Price) x 100
Gain Percentage = (0.6x / x ) x 100
Gain Percentage = 0.6 x 100 = 60%
Answer: The gain is 60%
