Open in App
Solution

  • The given bar graph shows the number of people and their preference for ice cream flavors.
  • Scale on the given bar graph:
    1 division = 10 people
  • Total divisions in the bar representing vanilla ice cream: 7×10 people =70 people
  • The bar for vanilla ice cream ends halfway between 70 and 80.
  • When a bar ends halfway between two grid lines, the value of the bar is halfway between the two numbers on the scale.
  • So, the number between 70 and 80 is 75.
  • Therefore, 75 people prefer vanilla ice cream.
Hence, option B is correct.
