问答题

某工程项目施工承包合同价为3200万元,工期18个月。承包合同规定:
1.发包人在开工前7天应向承包人支付合同价20%的工程预付款。
2.工程预付款自工程开工后的第8个月起分5个月等额抵扣。
3.工程进度款按月结算:工程质量保证金为承包合同价的5%,发包人从承包人每月的工程款中按比例扣留。
4.当分项工程实际完成工程量比清单工程量增加10%以上时,超出部分的相应综合单价调整系数为0.9。
5.规费费率3.5%,以工程量清单中分部分项工程合价为基数计算;税金率3.41%,按规定计算。
在施工过程中,发生以下事件:
(1)工程开工后,发包人要求变更设计,增加一项花岗石墙面工程,由发包人提供花岗石材料,双方商定该项综合单价中的管理费、利润均以人工费与机械费之和为计算基数,管理费率为40%,利润率为14%。消耗量及价格信息资料见表9-1。

(2)在工程进度至第8个月时,施工单位按计划进度完成了200万元建安工作量,同时还完成了发包人要求增加的一项工作内容。经工程师计量后的该工作工程量为260m2,经发包人批准的综合单价为352元/m2
(3)施工至第14个月时,承包人向发包人提交了按原综合单价计算的该月已完工程量结算报告180万元。经工程师计量,其中某分项工程因设计变更实际完成工程数量为580m3(原清单工程数量为360m3,综合单价1200元/m3)。
[问题]

(注:计算结果均保留两位小数,问题3和问题4的计算结果以万元为单位)

单项选择题

在墨西哥度假

Each year more travelers are finding their way to the sun coasts of Mexico; where ancient civilizations once honored the sun, modern sun worshippers are discovering superb vacation destinations. Airlines now schedule weekly flights from major national and international points to a variety of sun coast resort areas.

The peninsula of Baja California provides one of the most splendid vacation sites in the Western Hemisphere. The peninsula is divided into two states: Baja California Norte and Baja California Sur, which are now connected by the Benito Ju rez Trans-peninsular Highway, so that the entire peninsula can be easily reached by car, as well as by sea and air. A chain of new hotels offer deluxe accommodations, but there are also numerous camping grounds, trailer parks and wayside inns for those who prefer casual-living vacations. At the southern end of the peninsula, La Pazi San Jos del Cabo and Cabo San Lucas offer rapidly expanding deluxe facilities to accommodate the growing influx of visitors. All have good accommodations, restaurants, sports facilities and meeting rooms. In addition, La Paz, with its duty-free zone, is a shopper’s paradise.

Kino Bay, a coastal resort on the mainland near Hermosillo, is expanding and will soon offer new luxurious tourist accommodations.

South along the coast are Topolobampo and Los Mochis, the former a ferry terminus serving La Paz on the peninsula, and boasting the largest natural bay in the world; and the latter a starting point for the Chihuahua-Pacific Railway trip which goes through the breath-taking Copper Canyon to the city of Chihuahua.

Mazatlan, the sailfish capital of the world, has developed a large new resort complex to accommodate its many visitors. Famous for its jumbo shrimp and other delicious seafood, Mazatlan also offers seasonal bullfights, lively evening entertainment and big-game fishing. An international fishing tournament is held there each fall. Modem convention and sports facilities are available. Mazatlan is easily reached from other major cities by good high-ways and an international aiport.

Puerto Vallarta, once a sleepy fishing village, is now one of Mexico’s fastest growing resorts. The red-tiled roofs and cobblestoned streets contrast with the luxurious new hotels. The annual temperature averages around 80°F., offering a perfect climate for parasailing, skin diving, surfing and other aquatic sports. Evening entertainment includes seafood dinners, floor shows and disco dancing that lasts until daybreak. Big-game hunting and fishing are also popular within this region of coastal Mexico.

The world’s largest natural bay is located in()

A.Topolobampo and Los Mochis

B.Los Mochis

C.Mazatlan

D.Topolobampo
