The wages of workers (W1, W2, W3, W4, W5, W6) for different tasks (T1, T2, T3) are given
What is the difference in average wages per worker for task T1 and task T3?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 1/3
The average wages per worker for task T1 = (3 + 5 + 4 + 3 + 2 + 4)/6 = 21/6
The average wages per worker for task T3 = (4 + 3 + 4 + 5 + 4 + 3)/6 = 23/6
Hence, The difference in average wages per worker for task T1 and task T3 = (23 - 21) /6 = 2/6 = 1/3
