答案 A
解析 The correct answer is A. To solve this problem, you must determine the value of each quantity. Quantity A is(30% of 50)+40. Because 30% of 50 can be represented as 0.30(50), or 15, the quantity(30% of 50)+40 = 15+40, or 55. Similarly,(50% of 40)+ 30=0.50(40)+ 30, or 20 + 30, which equals 50. Thus, Quantity A(55)is greater than Quantity B(50).
