Answer:
c. 15 chairs/worker/day
Explanation:
Given the following information,
Number of employees = 6
Average number of chairs assembled = 450
Number of days = 5
The average number of chars assembled by per worker per day
= 450/(6 × 5)
= 450/30
= 15
It means that 1 worker would assemble an average of 15 chairs per day.
Option c. 15 chairs/worker/day is right.
