Heather has 35 stamps in her stamp collection. The stamps are divided into three groups: old, new and foreign. The number of stamps in the old group is one half of the number of stamps in the new group and one seventh of the total amount of stamps. How many foreign stamps does Heather have?

Answer(s): B

Explanation:

If the number of old stamp is 1/7 of the total amount, then there are 5 old stamps. Five old stamps are 1/2 of the new ones so there are 10 new stamps, therefore there are (35 – 10 – 5 = 20) foreign stamps.

QUESTION: 408

Elizabeth is interested in dividing the rooms in the house among the family. Unfortunately, they do not divide equally. It turns out that in order for the rooms to be dividable, Elizabeth has to build two more rooms and kick out one of the family members. Which of the following can describe the number of the initial rooms in the house and the initial number of family members (in the order Rooms, family)?

20; 8.
30; 9.
15; 6.
10; 5.
22; 10.

Answer(s): B

Explanation:

First we can eliminate answers where the number of rooms can be divided by the number of people, such as answer D.
We are looking for an answer that if you subtract 1 from the right and add 2 to the left, the left number will be divisible by the right number.
The only answer that fits this description is B. (30 +2)/(8) = 4.
