Q. If a group of friends is divided into two teams, and one team has 3 more members than the other, how many members are in each team if the total number of friends is 11?

A. 4 and 7
B. 5 and 6
C. 3 and 8
D. 2 and 9

Solution

Let the smaller team have x members. Then the larger team has x + 3 members. The equation is x + (x + 3) = 11, which simplifies to 2x + 3 = 11. Solving gives x = 4, so the teams have 4 and 7 members.

Correct Answer: A — 4 and 7

Q. If a group of friends is divided into two teams, and one team has 3 more members than the other, how many members are in each team if the total number of friends is 15?

A. 6 and 9
B. 7 and 8
C. 5 and 10
D. 4 and 11

Solution

Let x be the number of members in the smaller team. Then the larger team has x + 3 members. The equation is x + (x + 3) = 15, which simplifies to 2x + 3 = 15. Solving gives x = 6, so the teams have 6 and 9 members.

Correct Answer: B — 7 and 8

A. 162 hectares
B. 170 hectares
C. 180 hectares
D. 190 hectares

Solution

After 1 year: 200 - (10% of 200) = 180; After 2 years: 180 - (10% of 180) = 162; After 3 years: 162 - (10% of 162) = 145.8, rounded to 146 hectares.

D. 75.0

Solution

After 1 year: 100 - (10% of 100) = 90. After 2 years: 90 - (10% of 90) = 81. After 3 years: 81 - (10% of 81) = 72.9 species remain.

Correct Answer: A — 70.4

Q. If a habitat loses 25% of its biodiversity, and originally had 120 species, how many species remain?
