: (C)11又1/9%
: (D)12又1/2%
: (E) 15%
: 答案是B
这题是不是少给了几%??
: 27. To obtain an FHA mortgage for $50,000 or more, the home buyer must have a
: down payment equal to 4 percent of the first $25,000 of the mortgage amount
: and 5 percent of the portion in excess of $25,000. At settlement the buyer
: pay a mortgage insurance premium equal to 3 percent of the mortgage amount.
: What is the maximum FHA mortgage, if any a buyer can obtain if the buyer has
: only $6,000 available for the down payment and insurance premium?
: (A) $62,500
: (B) $71,875
: (C) $78,125
: (D) $125,00
: (E) The home buyer cannot obtain an FHA mortgage
: 答案是C
它是说为了获得大约是50,000或者超过的mortage(不知道是啥)
买家必须先附出25000*0.04=1000
在来还要付出总mortage数扣掉25000的0.05
最後在付出总mortage的0.03
问你若是买家手上现金有6000,那他最多能拿到多少的mortage
所以假设总mortage=50000+x
(25000*0.04)+(25000+x)*0.05+(50000+x)*0.03=6000
x=28125
总mortage=50000+28125=78125
: =,=一整个不知道怎麽算
: 就连知道答案後也配不出那个数字
: 请各位帮忙 谢谢<(_ _)>
: ps.by the way.. 笔试除了两回Q跟两回V之外
: 还会有多一回V/Q不计分的吗
: 那监考员会告诉我它是不计分的吗
