Solution

We will look at the height of each bar to find the expenditure for each item.

Step 1 — Find the highest expenditure

Let us read the expenditure for each item from the graph. House rent expenditure is 3000 rupees. Food expenditure is 3400 rupees. Education expenditure is 800 rupees. Electricity expenditure is 400 rupees. Transport expenditure is 600 rupees. Miscellaneous expenditure is 1200 rupees. We compare all these numbers. The largest number is 3400. This corresponds to Food.

Most spent on: Food\boxed{\text{Most spent on: Food}}

Diagram 1

Step 2 — Find the second highest expenditure

We already found the highest expenditure is 3400 for Food. Now we look at the remaining expenditures. These are 3000, 800, 400, 600, 1200. We compare these numbers. The largest among these is 3000. This corresponds to House rent.

Second most spent on: House rent\boxed{\text{Second most spent on: House rent}}

Answer

(i) Imran's family spends the most on Food. (ii) Imran's family spends the second most on House rent.
