An item (Burger) is sold at a profit of 20%. Determine the cost price of the item (Burger). Statement I: The selling price exceeds the cost price by Rs. 45. Statement II: If the selling price were Rs. 36 higher, the profit would become 36%.

ATQ, Let the cost price of the item be Rs. '100x' So, selling price of the item = 100x X 1.2 = Rs. '120x' Statement I: According to the statement: 120x - 100x = 45 Or, 20x = 45 So, x = 2.25 So, cost price of the item = 100x = 100 X 2.25 = Rs. 225 So, data in statement I alone is sufficient to answer the question. Statement II: According to the statement: 120x + 36 = 100x X 1.36 Or, 120x + 36 = 136x So, 16x = 36 So, x = 2.25 So, cost price of the item = 100x = 100 X 2.25 = Rs. 225 So, data in statement II alone is sufficient to answer the question. So, data either in statement I alone or in statement II alone is sufficient to answer the question. Statement II: According to the statement: 120x + 36 = 100x X 1.36 Or, 120x + 36 = 136x So, 16x = 36 So, x = 2.25 So, cost price of the item = 100x = 100 X 2.25 = Rs. 225 So, data in statement II alone is sufficient to answer the question. So, data either in statement I alone or in statement II alone is sufficient to answer the question.
