Re: [計量] 二題CAT計量提問..
※ 引述《ocupy (束縛不住的枷鎖)》之銘言:
: 1.
: A customer purchased a one-year applicance service contract that cost $15
: and covered payment of 75 percent of each repair bill. For one year, the cost
: of the contract together with the total amount of the repair bills not
: covered by the contract was equal to the total amount covered by the contract.
: What was the total amount of repair bills for the year?
: (A)$30 (B)$20 (C)$15 (D)$10 (E)$5
: Ans: (A)
本題題意相當難懂,應該是說這個服務合約要15元,而它可以付你所有修理費的百分之
七十五,而這一年中,花費的合約加上所有的修理費(不包含合約覆蓋的部份),剛好等於
合約覆蓋的部份,問此年共花多少修理費?
設修理費x
0.25x+15=0.75x ==> x=30
: 2.
: The product og three positive consecutive even integers must be divisible by
: each of the following Except
: (A)48 (B)32 (C)16 (D)8 (E)6
: Ans: (B)
這題連續三個偶數,所以找最小的測驗==> 2*4*6=48
故選32
: 兩題煩請大家幫忙囉!第一題題意真的是不太懂耶@@...
