How to approach this question

1. Look at the relationship between the 'females' column and the 'males' column for the rows where you have data. 2. Calculate the approximate ratio or pattern. (e.g., 143 is about double 70; 95 is about double 43). 3. You should notice that the number of males is consistently about half the number of females. 4. Apply this pattern to the 'Work issues' row. The number of females is 97. 5. Calculate half of 97 (which is 48.5) and choose the option closest to your calculation.

Full Answer

B.45✓ Correct
This question tests your ability to analyse data and extrapolate from a pattern. By examining the pairs of numbers (143, 70), (95, 43), (105, 60), (126, 71), and (128, 67), a consistent pattern emerges: the number in the female column is approximately twice the number in the male column. To estimate the missing value, we apply this pattern to the 'Work issues' row. Given 97 females, the expected number of males would be around 97 / 2 = 48.5. The closest option provided is 45.

Common mistakes

Simply guessing without identifying the mathematical pattern present in the data table.
