Q. In a basketball game, a player scores 15 points in the first half and 20 points in the second half. What is the ratio of points scored in the first half to the total points scored? (2020)
A.
3:7
B.
3:5
C.
5:7
D.
2:5
Solution
Total points scored = 15 + 20 = 35. The ratio of points scored in the first half to total points is 15:35, which simplifies to 3:7.
Q. In a basketball game, a player scores 15 points in the first half and 20 points in the second half. What is the player's average score per half? (2020)
A.
15
B.
17.5
C.
20
D.
18
Solution
Total points scored = 15 + 20 = 35. Average score per half = 35 / 2 = 17.5.
Q. In a certain plant species, tall (T) is dominant over short (t). If a homozygous tall plant is crossed with a homozygous short plant, what will be the genotype of the offspring?
A.
TT
B.
Tt
C.
tt
D.
Tt and tt
Solution
The homozygous tall plant (TT) crossed with a homozygous short plant (tt) will produce all offspring with the genotype Tt.
Q. In a certain species of fruit flies, the allele for red eyes (R) is dominant over the allele for white eyes (r). If two red-eyed flies, one homozygous (RR) and one heterozygous (Rr), are crossed, what percentage of the offspring will have white eyes?
A.
0%
B.
25%
C.
50%
D.
100%
Solution
The cross RR x Rr will produce all red-eyed offspring (100% R). Thus, 0% will have white eyes.
Q. In a certain species of pea plants, round seeds (R) are dominant over wrinkled seeds (r). If a round seed plant with genotype Rr is crossed with a wrinkled seed plant (rr), what is the expected genotype ratio of the offspring?
A.
1:1
B.
3:1
C.
1:2:1
D.
2:1
Solution
The cross Rr x rr results in 1 Rr (round) and 1 rr (wrinkled), giving a genotype ratio of 1:1.
Q. In a certain species, the allele for blue eyes (b) is recessive to the allele for brown eyes (B). If a brown-eyed man (Bb) marries a blue-eyed woman (bb), what is the probability that their child will have blue eyes?
A.
0%
B.
25%
C.
50%
D.
100%
Solution
The cross Bb x bb results in 50% Bb (brown) and 50% bb (blue), so the probability of having a blue-eyed child is 50%.
Q. In a certain species, the allele for blue eyes (b) is recessive to the allele for brown eyes (B). If two heterozygous brown-eyed individuals (Bb) have children, what is the probability that a child will have blue eyes?
A.
0%
B.
25%
C.
50%
D.
75%
Solution
The cross Bb x Bb results in a 1/4 chance of bb (blue eyes), so the probability is 25%.
Q. In a certain species, the allele for blue flowers (B) is dominant over the allele for white flowers (b). If two blue-flowered plants, one homozygous (BB) and one heterozygous (Bb), are crossed, what percentage of the offspring will have white flowers?
A.
0%
B.
25%
C.
50%
D.
100%
Solution
The cross BB x Bb will produce 100% blue flowers (BB or Bb), so 0% will have white flowers.
Q. In a certain species, the allele for blue flowers (B) is dominant over the allele for white flowers (b). If two blue-flowered plants, both heterozygous (Bb), are crossed, what is the expected phenotypic ratio of the offspring?
A.
1:1
B.
3:1
C.
1:2:1
D.
2:1
Solution
The cross Bb x Bb results in a phenotypic ratio of 3 blue (BB or Bb) to 1 white (bb), which is 3:1.
Q. In a certain species, the allele for long tails (L) is dominant over the allele for short tails (l). If a long-tailed individual is crossed with a short-tailed individual, what is the expected genotype of the offspring if the long-tailed individual is heterozygous?
A.
LL
B.
Ll
C.
ll
D.
LL or Ll
Solution
The cross Ll x ll will produce offspring with genotypes Ll and ll, so the expected genotype is Ll.
Q. In a certain species, the allele for tall plants (T) is dominant over the allele for short plants (t). If a tall plant (Tt) is crossed with a short plant (tt), what is the expected genotypic ratio of the offspring?
A.
1:1
B.
3:1
C.
1:2:1
D.
2:1
Solution
The cross Tt x tt results in a genotypic ratio of 1 Tt (tall) to 1 tt (short), which is 1:1.
Q. In a certain species, the allele for tall plants (T) is dominant over the allele for short plants (t). If two heterozygous tall plants (Tt) are crossed, what is the expected phenotypic ratio of the offspring?
A.
1:2:1
B.
3:1
C.
9:3:3:1
D.
1:1
Solution
The expected phenotypic ratio from Tt x Tt is 3 tall: 1 short, which is a 3:1 ratio.
Q. In a certain year, the Parliament passed 120 bills. If 30% of these bills were passed in the Lok Sabha, how many bills were passed in the Lok Sabha?
A.
30
B.
36
C.
40
D.
42
Solution
Bills passed in Lok Sabha = 30% of 120 = 0.30 * 120 = 36.
Q. In a certain year, the Parliament passed 150 bills. If 60% of these bills were passed in the Lok Sabha, how many bills were passed in the Lok Sabha?
A.
90
B.
80
C.
70
D.
60
Solution
Bills passed in Lok Sabha = 60% of 150 = 0.6 * 150 = 90.
Q. In a clinical trial, 60% of patients showed improvement after treatment. If 150 patients were treated, how many patients are expected to show improvement? (2022)
