Question : 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?
Option 1:
Option 2:
Option 3:
Option 4:
Correct Answer:
Solution :
As per the given graph,
The number of workers = 6
The total number of wages for T3 = 3 + 4 + 5 + 4 + 3 + 4 = 23
The average for T3 =
The total number of wages for T1 = 4 + 2 + 3 + 4 + 5 + 3 = 21
The average for T3 =
The required difference =
Hence, the correct answer is
