Show answer & explanation
Correct answer: B
The average of a set of values equals their total sum divided by the number of values: Average = (Sum of all values) / (Number of values). In a data-interpretation table, always read each entry directly from the row and column being asked about before adding them, since a single misread figure will shift the sum and the final average.
From the table, the 2007 sales figures for the six showrooms are: Showroom A = 178, Showroom B = 272, Showroom C = 269, Showroom D = 95, Showroom E = 379, Showroom F = 198.
Sum of these six figures = 178 + 272 + 269 + 95 + 379 + 198 = 1391.
Number of showrooms = 6.
Average = 1391 / 6 ≈ 231.8.
Checking against the options given, 231.8 is nearest to one of the values by a margin of only about 2, while every other option differs from it by more than 16 — confirming which option the intended average corresponds to.
So the average number of mobile phones sold by all showrooms in 2007 is closest to 234.
