So, he can meet maximum 4 athletes (at places - B, A, D, and E) on his way.

Test Level 1: Critical Path - Question 12

Directions: Study the following information carefully and answer the question that follows.
Six levels of a game – A through F – are connected by a few two-way paths, as shown below. To travel along any path directly connecting any two ways, a person has to collect some points. In the figure below, the length of each path (in m) is indicated by the number, and the points a person can collect are written inside the square adjacent to the path. Direction of the arrow is representing the different paths they can follow.

If two players are playing a game and want to score equal points but both cannot take same route, then which routes should they follow such that the total distance covered remains more than 10 m for each of them?

Detailed Solution for Test Level 1: Critical Path - Question 12

If they take routes A-B-F and A-C-D-F, they will have equal points.
(i) A-B-F
A to B = 150 points
B to F = 100 points
Total = 100 + 150 = 250 points
Distance from A to B = 6 m and from B to F = 5 m
Total distance = 6 + 5 = 11 m
(ii) A-C-D-F
A to C = 60 points
C to D = 70 points
D to F = 120 points
Total = 60 + 70 + 120 = 250 points
Distance from A to C = 4 m, from C to D = 3 m, and from D to F = 4 m
Total distance = 4 + 3 + 4 = 11 m

Test Level 1: Critical Path - Question 13

Directions: Study the following information carefully and answer the question that follows.

In the figure below, the length of each path (in m) is indicated by the number, and the points a person can collect are written inside the square adjacent to the path. Direction of the arrow is representing the different paths they can follow.

If points at all the pathways are reduced to half and distance has been doubled, then what would be the pathway between A and F with highest points but not with the shortest distance?

Detailed Solution for Test Level 1: Critical Path - Question 13

(i) A-B-F
Points = 150 + 100 = 250, Half of 250 = 125
Distance = 6 + 5 = 11, Double of 11 = 2
(ii) A-C-E-D-F
Points = 60 + 40 + 100 + 120 = 320, Half of 320 = 160
Distance = 4 + 2 + 3 + 4 = 13, Double of 13 = 26
(iii) A-C-D-F
Points = 60 + 70 + 120 = 250, Half of 250 = 125
Distance = 4 + 3 + 4 = 11, Double of 11 = 22
(iv) A-C-B-F
Points = 60 + 50 + 100 = 210, Half of 210 = 105
Distance = 4 + 5 + 5 = 14, Double of 14 = 28
