In the question, it is already given that the total number of runners in the race is 60 and out of them 1/3 dropped out in the first half. In the second half 1/4 of the remaining runners dropped out.
Now
Total number of runners in the race = 60
Number of runners that dropped out in the first half = 1/3 * 60
= 20
Number of runners remaining = 60 - 20
= 40
Number of runners dropping out in the second half = 40 * 1/4
= 10
Then the number of runners that finished the race = 40 - 10
= 30
Then 30 runners completed the race.

Step-by-step explanation:
25% is equal 25/100 which simplified to 1/4
The two angles are identical:
3x -7 = 2x + 7
Add 7 to both sides:
3x = 2x + 14
Subtract 2x from both sides:
X = 14
