Q. If a train travels from City A to City B in 2 hours and returns in 3 hours, what is the average speed of the train for the entire journey if the distance is 120 km each way?
A.
40 km/h
B.
60 km/h
C.
80 km/h
D.
100 km/h
Solution
Total distance is 240 km and total time is 5 hours, so average speed is 240/5 = 48 km/h.
Q. If a train travels from City A to City B in 2 hours and returns in 3 hours, what is the average speed of the train for the entire journey if the distance is 120 km one way?
A.
40 km/h
B.
60 km/h
C.
80 km/h
D.
100 km/h
Solution
The total distance is 240 km and the total time is 5 hours, giving an average speed of 48 km/h.
Q. If a trait is controlled by a single gene with two alleles, where A is dominant over a, what is the expected phenotypic ratio in the offspring of a cross between Aa and aa?
A.
1:1
B.
3:1
C.
2:1
D.
1:2
Solution
The cross Aa x aa will produce offspring in a 1:1 phenotypic ratio (A:a).
Q. If a trait is sex-linked and recessive, what is the probability that a son will express the trait if his mother is a carrier and his father does not have the trait?
A.
0%
B.
25%
C.
50%
D.
100%
Solution
The son will inherit the X chromosome from his mother. If she is a carrier (X^HX^h), there is a 50% chance he will inherit the X^h and express the trait.
Q. If a treatment is effective in 80% of cases, what is the probability that it will be effective for at least one out of three patients? (2023)
A.
0.512
B.
0.8
C.
0.2
D.
0.64
Solution
Probability that treatment is not effective for one patient = 1 - 0.8 = 0.2. For three patients, the probability that it is not effective for all = 0.2^3 = 0.008. Therefore, the probability that it is effective for at least one = 1 - 0.008 = 0.992.
