Show answer & explanation

Correct answer: C

Concept: The average (mean) of a set of values is the sum of all the values divided by how many values there are. When a data-interpretation table gives figures in a common unit (here, thousands of workers), add every relevant figure first, then divide by the count of figures, to get the average in that same unit.

Application: For Factory P, the six shift-wise figures (in thousands) from the table are 8.32, 7.5, 7.24, 6.5, 5.7 and 2.15.

  1. Add the six shift figures for Factory P: 8.32 + 7.5 = 15.82; 15.82 + 7.24 = 23.06; 23.06 + 6.5 = 29.56; 29.56 + 5.7 = 35.26; 35.26 + 2.15 = 37.41 (thousand).

  2. Divide the total by the number of shifts (6): 37.41 ÷ 6 = 6.235 (thousand).

  3. Convert to the actual number of workers: 6.235 × 1000 = 6235.

Cross-check: Multiplying the average back by the number of shifts, 6.235 × 6 = 37.41, which matches the sum of the six shift figures for Factory P — confirming the average number of workers across the six shifts is 6235.
