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?

$\frac{1}{3}$

Average wagers for T1 = \(\frac{3 + 5 + 4 + 3 + 2 + 4 }{6}\)

= \(\frac{21}{6}\)

Average wagers for T3 = \(\frac{4 + 3 + 4 + 5 + 4 + 3 }{6}\)

= \(\frac{23}{6}\)

Required difference = \(\frac{23}{6}\)  - \(\frac{21}{6}\) 

= \(\frac{1}{3}\)
