del 10% de la misma cantidad?
A) 5,5%
B) 5,83% C) 4,8%
D) 5%



Answer :

To solve the given problem, we need to break it down step by step: 1. Calculate the expression: 20% of 80% of 140% of a quantity: - First, find 80% of 140%, which is 0.8 * 1.4 = 1.12. - Then, find 20% of 1.12, which is 0.2 * 1.12 = 0.224. 2. Calculate the expression: 7/25 of 40% of 10% of the same quantity: - First, find 10% of 40%, which is 0.1 * 0.4 = 0.04. - Then, find 7/25 of 0.04, which is (7/25) * 0.04 = 0.0112. 3. Compare the two results: - The first expression is 0.224 and the second expression is 0.0112. - To find what percentage the second expression is of the first expression, we divide the second expression by the first expression: 0.0112 / 0.224 = 0.05 = 5%. Therefore, the answer is: D) 5%
