不管怎樣，CFA考試即便考很多定性的考試題，但是還是有定量的考試題的，考生在備考中也是要練習的，不管怎樣，跟著小編一起看看吧！
A consumer has a budget of $30 per month tospend on two types of fruit, priced as follows:
·Apples: $2.50 perpound.
·Bananas: $2.00 perpound.
Assuming the quantity of apples is measured on the verticalaxis and bananas on the horizontal axis, the slope of the budget constraint isclosest to:
A．1.25.
B．-0.80.
C．-1.25.
【答案】B
【解析】
The budget constraint is given by the formula: 2.5 QA+ 2.0 QB = 30, where QA and QB are quantities ofapplesand bananas purchased, respectively. With the quantity of apples measured onthe vertical axis, the slope is equal to -(PB/PA) =-(2.00/2.50) = - 0.8, where PA and PB are prices ofapplesand bananas, respectively.
