The monthly cost for zone 2 is $17.5

Erklärung:

Look at the other content writers to see if any of them can be scheduled to join Bonnie and Donna for lunch during the 1:00 PM-1:30 PM shift: 

Anne – According to the passage, Anne and Donna never go to lunch at the same time. Thus, Anna cannot be scheduled to join Bonnie and Donna for lunch.

Jordan– According to the passage, Jordan never goes to lunch during the 1:00 PM-1:30 PM shift. Thus, Jordan cannot be scheduled to join Bonnie and Donna for lunch.

Mike – According to the passage, Mike never joins Bonnie for lunch. Thus, Mike cannot be scheduled to join Bonnie and Donna for lunch. 

Francine – According to the passage, Francine and Harriet always go to lunch together. However, if both Francine and Harriet go with Bonnie and Donna to lunch, then there will be four content writers taking lunch at the same time. According to the passage, no more than three content writers can be scheduled to go to lunch during the same shift. Therefore, Francine cannot be scheduled to join Bonnie and Donna for lunch.

Georgia – According to the passage, Georgia never joins Bonnie for lunch. Thus, Georgia cannot be scheduled to join Bonnie and Donna for lunch.

Harriet – According to the passage, Francine and Harriet always go to lunch together. However, if both Francine and Harriet go with Bonnie and Donna to lunch, then there will be four content writers taking lunch at the same time. According to the passage, no more than three content writers can be scheduled to go to lunch during the same shift. Therefore, Francine cannot be scheduled to join Bonnie and Donna for lunch.

Since none of the other content writers can be scheduled to join Bonnie and Donna for lunch, the correct answer is (D).

Die Zahlenreihe folgt den Regeln: +10, :2, :2, +10 usw.

Erkennt man die Regel, ist die Aufgabe einfach zu lösen. Unter Zeitdruck fällt es den meisten von uns schwerer, solche Regeln zu erkennen. Mit etwas Übung aber, schärfen Sie Ihren Blick und können solche Zahlenreihen schnell und souverän lösen.

Wie angegeben, löscht A das dritte Symbol, während B das zweite Symbol dupliziert. Was macht C? 

Sehen Sie sich dazu dritte Zeile in der Illustration genauer an. A löscht die dritte Figur, den großen blauen Kreis.

Dann erhalten wir einen großen lila Kreis, einen kleines, blaues Quadrat und einen kleinen, blauen Kreis. 

Um zum Output zu gelangen (großer lila Kreis, zwei kleine blaue Quadrate, kleiner blauer Kreis) muss der Operator C also das zweite Symbol duplizieren.

Mit dieser Information gehen Sie nun an die eigentliche Aufgabe: 

Die Antwortmöglichkeiten 2 und 3 können Sie zuerst ausschließen. Der Grund: Da der Operator A das dritte Symbol löscht, können B und C sie nicht duplizieren.

Somit bleiben zwei mögliche Antworten: 1 und 4.

Überprüfen Sie also zunächst Option 1:

Die Symbolfolge ist die richtige!

Tipp: Es ist hilfreich und zeitsparend, zunächst die "unmöglichen" Optionen zu eliminieren und dann die übrigen Szenarien durchzuspielen.

First of all, let’s calculate the new costs of Bared-type products, as well as the new prices of Calir-type products (be aware not to confuse 0.7% with 7% and 0.3% with 3%):
Cost of Bared 120: (236+37+95)*(1-0.007) = £365.424
Cost of Bared 260: (268+37+96)* (1-0.007) = £398.193
Cost of Bared 450: (320+38+130)* (1-0.007) = £484.584
Price of Calir XC: 1,734*(1+0.003) = £1,739.202
Price of Calir XR: 2,326*(1+0.003) = £2,332.978

Now we can find the profit gained from selling one unit of each product (profit = sell price – total cost):
Profit from one unit of Bared 120: 792-365.424 = £426.576
Profit from one unit of Bared 260: 797-398.193 = £398.807
Profit from one unit of Bared 450: 987-484.584 = £502.416
Profit from one unit of Calir XC: 1,739.202-(408+56+240) = £1,035.202
Profit from one unit of Calir XR: 2,332.978-(432+57+256) = £1,587.978

Finally, we can calculate the total profit:
(270*426.576)+(270*398.807)+(270*502.416)+(350*1,035.202)+(350*1,587.978)

Tip: in order to simplify the calculation, we can pull out the common factors:
[270*(426.576+398.807+502.416)]+[350*(1,035.202+1,587.978)] = 1,276,618.73 ≈ 1.277 million

Erklärung:

When looking for common ground, one should keep in mind that we are looking for a piece of information that appears or is inferred in both passages.

Perhaps you have already noticed that Cole and Trefethen have quite opposite ideas regarding the BMI. While Cole considers it to be a simple, cheap and sufficient measure of obesity, Trefethen views it as inaccurate and out dated.

This information can help us disqualify distracters B and C, which seem to go hand in hand with Trefethen's opinion of the BMI, yet contradict Cole's viewpoint.

Distracter D may also be disqualified, since Cole dismisses MRIs and other scans as a fitting measure for measuring obesity.

Distracter A is the correct answer- Cole explicitly speaks of the simplicity of the BMI, while Trefethen speaks of it implicitly, when mentioning the origin of the BMI: “It was invented in the 1840s, before calculators, when a formula had to be very simple and usable.”

Es gibt zwei Eigenschaften, denen Sie in dieser Serie folgen müssen: X und O.

Diese Aufgabenstellung soll verwirren. Man ist zunächst geneigt, auf die Positionen von X und O und nicht auf deren Häufigkeit zu achten. Genau letzeres sollten Sie aber tun. 

Dann erschließt sich, dass sich die Anzahl von X in jedem Quadrat um eins erhöht, wenn Sie sich entlang der Reihe bewegen: 3, 4, 5, 6.

Gleichzeitig nimmt die Anzahl von O für jedes Quadrat ab: 6, 5, 4, 3.

Das gesuchte Quadrat muss daher 7 X und 2 O enthalten.

Alle Objekte mit Ausnahme von (1) beinhalten symmetrische Muster, die sich entlang einer (unsichtbaren) Linie von links unten nach rechts oben im Quadrat spiegeln.

Objekt (1) müsste diese Linie von rechts unten nach links oben gezogen werden.

Tipp: Lassen Sie sich nicht durch die Anzahl der Punkte oder deren Farben verwirren.

Für ein ungeübtes Auge kann es schwierig sein, die Regel zu erkennen. Sobald Sie aber eine Reihe von Aufgaben geübt haben, werden Sie Regelmuster schneller und effizienter identifizieren.

Erklärung:

In jeder Reihe und in jeder Spalte gibt es ein Symbol, das zweimal erscheint.

In der zweiten Reihe gibt es bereits ein Symbol, das zweimal vorkommt: Der Pfeil nach rechts. Sie suchen also nach einer Symbolkombination, die weder einen Pfeil nach rechts, noch ein Pentagon oder Dreieck an dieser Stelle besitzt. 

So können Sie die Antwortoptionen 1, 2 und 4 eliminieren. 

Nun sehen Sie sich die erste Reihe an, wo noch keines der Symbole zweimal erscheint. Die richtige Antwort muss also eines der bereits vorhandenen Symbole (Dreieck, Raute, Pfeil nach links) beinhalten. 

Das trifft auf Antwort 5 nicht zu; auf Antwort 3 aber schon. 

Lösungstipp: Bei solchen Matrizen ist es sinnvoll, zunächst nach bestehenden Mustern zu suchen. Anhand dieser können Sie dann beginnen, Antwortmöglichkeiten zu eliminieren und gelangen nach dem Ausschlussprinzip zur richtigen Lösung. 

Erklärung:

The key to solving this problem is to figure out the sums (percentages) for each statement. If the results are greater than 100%, we can identify an overlap between categories.

Answer (A) - Half of Georgia’s coke-drinking inhabitants are Native Americans. If 60% of inhabitants drink Coke, then the Native American inhabitants that drink Coke make up 30% of Georgia's total population. And 30% of Georgia's inhabitants are Native Americans, so the sum of the two groups is 60% (i.e. 30% + 30%= 60% < 100%) of the population. There isn't a definite overlap between the categories.

Answer (B) - One-third of Georgia's coke-drinking inhabitants is 20% (1/3*60) and 20% of Georgia's inhabitants work in agriculture (i.e. 20% + 20%= 40% < 100%). However, there is no indication of overlap between the two groups.

Answer (C) - Whether there is an overlap between Georgia's Native American inhabitants and the service industry and agriculture workers is unknown, as Georgia's Native American inhabitants constitute 30% of Georgia's population, and service industry and agriculture workers together constitute 70% of Georgia's population (i.e. 30% + 70%= 100%). Also, even if Native Americans are divided between working in the service industry and in agriculture, there is no way of knowing how they are divided among those jobs.

Answer (D) - According to the data provided, service industry workers constitute 50% of Georgia's population. Furthermore, cola drinkers constitute 60% of Georgia's population. This means there is a definite overlap between service industry workers and cola drinkers (i.e. 50% + 60%= 110% > 100%). Therefore, some of Georgia's service industry employees definitely drink Coke (at least 10% of them).

Answer (E) - Two extreme possibilities must be taken into consideration while testing the statement's validity:
1. There is no overlap between the agriculture workers and the coke drinkers - in that case they constitute 80% of Georgia's population, which means those who are neither agriculture workers nor coke drinkers constitute 20% of Georgia's population. One fifth of those 20% equals 4% which are claimed to be the percentage of Native Americans in Georgia's population. However, it is known that 30% of Georgia's population is Native American. Therefore, this option is invalid.
2. There is a full overlap between agriculture workers and coke drinkers - in that case they constitute 60% of Georgia's population, which means those who are neither agriculture workers nor coke drinkers constitute 40% of Georgia's population. One fifth of those 40% equals 8% which are claimed to be the percentage of Native Americans out of Georgia's population. However, it is known that 30% of Georgia's population is Native American. Therefore, this option is invalid.
