Solution
Understand the Question
  • A bar graph visually represents quantities through the heights of bars corresponding to each category.
  • To find the items with the highest and second highest spending, compare the values or bar heights for each expenditure category from the graph:
    • Food=3400\text{Food} = ₹3400
    • House rent=3000\text{House rent} = ₹3000
    • Miscellaneous=1200\text{Miscellaneous} = ₹1200
    • Education=800\text{Education} = ₹800
    • Transport=600\text{Transport} = ₹600
    • Electricity=400\text{Electricity} = ₹400

1 On which item does Imran’s family spend the most and the second most?

Step 1 · Find the Highest Expenditure

Read the expenditure for each item from the given bar graph:Diagram 1

  • Food:3400\text{Food}: ₹3400
  • House rent:3000\text{House rent}: ₹3000
  • Miscellaneous:1200\text{Miscellaneous}: ₹1200
  • Education:800\text{Education}: ₹800
  • Transport:600\text{Transport}: ₹600
  • Electricity:400\text{Electricity}: ₹400

Comparing all the values: 3400>3000>1200>800>600>4003400 > 3000 > 1200 > 800 > 600 > 400

The largest expenditure is 3400₹3400, which corresponds to Food.

Step 2 · Find the Second Highest Expenditure

Comparing the remaining expenditures (3000,1200,800,600,4003000, 1200, 800, 600, 400):

The highest among the remaining values is 3000₹3000, which corresponds to House rent.

Answer

1 Most: Food, Second most: House rent

Common Mistakes
  • Scale Misreading: Misreading intermediate values on the vertical axis (e.g., confusing 34003400 with 35003500).
  • Order Inversion: Listing the items in ascending order instead of identifying the top two highest expenditures.
