What is the average of the total number of candidates interviewed by BOB and by BOI from Monday to Friday?
A166
B178
C184 ✓ Correct
D218
Correct answer: (C) 184
Explanation
The answer is 184.
BOI from Monday to Friday interviewed 36, 38, 44, 28 and 20, totalling 166.
BOB from Monday to Friday interviewed 36, 50, 36, 36 and 44, totalling 202.
The average is half of the sum of these two totals.
So it is 166 plus 202, divided by 2.
That equals 368 divided by 2, which is 184.
So the answer is 184.
