Q. In a competition, a participant received a cash prize of $1500 for finishing first. If the total prize money was $6000, what fraction of the total prize money did he receive?
Q. In a competition, a participant received a gold medal for scoring 85% marks. If the total marks were 200, how many marks did the participant score? (2019)
Q. In a competition, the first prize is $500, the second prize is $300, and the third prize is $200. If the total amount awarded is $1000, what percentage of the total amount does the first prize represent? (2019)
A.
50%
B.
40%
C.
30%
D.
20%
Solution
Percentage of first prize = (500 / 1000) * 100 = 50%.
Q. In a dihybrid cross between two pea plants, one with genotype AaBb and the other with genotype Aabb, what fraction of the offspring will be homozygous recessive for both traits?
A.
1/16
B.
1/8
C.
1/4
D.
1/2
Solution
The cross AaBb x Aabb results in 1/8 of the offspring being aabb (homozygous recessive for both traits).
Q. In a dihybrid cross between two plants, one with genotype AaBb and the other with genotype Aabb, what fraction of the offspring will be expected to show the dominant phenotype for both traits?
A.
1/4
B.
1/2
C.
3/4
D.
1/8
Solution
The cross AaBb x Aabb results in 1/4 AABB, 1/4 AABb, 1/4 AaBb, and 1/4 Aabb. Only AABB, AABb, and AaBb show the dominant phenotype for both traits, which is 3 out of 8, hence 3/8.
Q. In a football match, a player scored 3 goals in the first half and 2 goals in the second half. What is the ratio of goals scored in the first half to the total goals scored? (2020)
A.
3:5
B.
2:5
C.
1:2
D.
3:2
Solution
Total goals scored = 3 + 2 = 5. The ratio of goals in the first half to total goals is 3:5.
Q. In a football match, a player scores 3 goals in the first half and 2 goals in the second half. What is the ratio of goals scored in the first half to the total goals scored? (2020)
A.
3:5
B.
2:5
C.
1:2
D.
3:2
Solution
Total goals scored = 3 + 2 = 5. The ratio of goals in the first half to total goals is 3:5.
Q. In a genetic experiment, a plant with genotype AaBb is crossed with another plant of genotype Aabb. What is the probability of obtaining an offspring with genotype Aabb?
A.
1/4
B.
1/2
C.
3/4
D.
1/8
Solution
The possible genotypes from the cross AaBb x Aabb are AaBb, Aabb, AABb, and Aabb. The probability of Aabb is 1/2.
Q. In a genetic study, if a trait is controlled by a single gene with two alleles, where one allele is completely dominant over the other, what is the expected genotypic ratio in the offspring of a monohybrid cross?
A.
1:2:1
B.
3:1
C.
1:1
D.
9:3:3:1
Solution
The expected genotypic ratio from a monohybrid cross is 1:2:1.
Q. In a genetic study, if a trait is controlled by a single gene with two alleles, where one allele is completely dominant over the other, what type of inheritance pattern is this?
A.
Codominance
B.
Incomplete dominance
C.
Complete dominance
D.
Polygenic inheritance
Solution
This describes complete dominance, where one allele completely masks the effect of the other.
Q. In a genetic study, if a trait is controlled by a single gene with two alleles, how many different genotypes can be formed from two heterozygous parents?
A.
1
B.
2
C.
3
D.
4
Solution
From two heterozygous parents (Aa x Aa), the possible genotypes are AA, Aa, and aa, resulting in 3 different genotypes.
Q. In a national election, if 65% of the votes are in favor of a candidate and there are 1,000,000 votes cast, how many votes did the candidate receive?
