Q. In a population of rabbits, black fur (B) is dominant over white fur (b). If two heterozygous black rabbits (Bb) are mated, what is the expected phenotypic ratio of their offspring?
A.
1:1
B.
3:1
C.
2:1
D.
1:2:1
Solution
The cross Bb x Bb results in 1 BB (black), 2 Bb (black), and 1 bb (white), giving a phenotypic ratio of 3:1.
Q. In a population of rabbits, the allele for black fur (B) is dominant over the allele for white fur (b). If 64% of the rabbits are black, what is the frequency of the recessive allele (b) in the population?
A.
0.36
B.
0.64
C.
0.25
D.
0.5
Solution
Using the Hardy-Weinberg principle, if 64% are black (BB or Bb), then 36% are white (bb). The frequency of b is √0.36 = 0.6.
Q. In a quiz competition, the first prize is $1000, the second prize is $500, and the third prize is $250. What is the total prize money awarded? (2000)
Q. In a quiz competition, the first prize is $1000, the second prize is $600, and the third prize is $400. What is the total prize money distributed? (2020)
Q. In a quiz competition, the first prize is $500, the second prize is $300, and the third prize is $200. If the total prize money is $1000, what percentage of the total prize money does the first prize represent? (2019)
A.
50%
B.
40%
C.
30%
D.
20%
Solution
First prize = $500. Total prize money = $1000. Percentage = (500/1000) * 100 = 50%.
Q. In a recent climate change agreement, 12 countries committed to reducing emissions by 20%. If the total emissions are 1 billion tons, how much will be reduced?
A.
100 million tons
B.
200 million tons
C.
300 million tons
D.
400 million tons
Solution
Reduction in emissions = 20% of 1 billion tons = 0.2 * 1 billion = 200 million tons.
Q. In a recent international summit, 25 countries participated. If each country sent 3 representatives, how many representatives were there in total? (2022)
A.
50
B.
60
C.
75
D.
80
Solution
Total representatives = 25 countries * 3 representatives = 75 representatives.
Q. In a right triangle, if one angle is 30 degrees, what is the ratio of the lengths of the sides opposite to the 30 degrees and 60 degrees angles? (2019)
A.
1:√3
B.
1:2
C.
√3:1
D.
2:1
Solution
In a 30-60-90 triangle, the sides opposite the 30 degrees and 60 degrees angles are in the ratio 1:√3.
Q. In a right triangle, if one angle is 45 degrees, what is the measure of the other non-right angle? (2021)
A.
30 degrees
B.
45 degrees
C.
60 degrees
D.
75 degrees
Solution
In a right triangle, the sum of the angles is 180 degrees. If one angle is 45 degrees and the right angle is 90 degrees, the other angle must be 180 - (90 + 45) = 45 degrees.
