Solution Steps

Step 1: Identify the number of people surveyed in each age group

From the bar graph:

  • 0-20: 250 people
  • 21-40: 400 people
  • 41-60: 550 people
  • 61-80: 300 people
Step 2: Calculate the total number of people surveyed

Sum the number of people in all age groups: \[ 250 + 400 + 550 + 300 = 1500 \]

Step 3: Calculate the percentage of people in the 41-60 age group

Use the formula for percentage: \[ \left( \frac{\text{Number of people in 41-60 age group}}{\text{Total number of people}} \right) \times 100 \] \[ \left( \frac{550}{1500} \right) \times 100 = 36.7\% \]

Final Answer

a) 36.7%
