How much does the family spend on Rent each month?

₹10,800. 30\% of ₹36,000 = 0.30 36000 = ₹10,800.

What is the central angle of the Food sector in the pie chart?

90°. 25\% of 360^ = 0.25 360 = 90^ .

How much more does the family spend on Food than on Education each month?

₹4,680. The difference is 25\% - 12\% = 13\% of ₹36,000 = 0.13 36000 = ₹4,680.

Transport and Savings together account for what fraction of the total budget?

14. Together they are 15\% + 10\% = 25\% = 14 of the budget.

Key formulas

Sector value $= \dfrac{\text{sector percent}}{100}\times \text{total}$
Degrees to percent: $\dfrac{\text{degrees}}{360}\times 100\%$ ; percent to degrees: $\dfrac{\text{percent}}{100}\times 360^\circ$
If a sector of $p\%$ equals value $V$ , the total is $\dfrac{V \times 100}{p}$

How much does the family spend on Rent each month?
4 steps · reveal one at a time
1. Step 1: Identify Key Information
  We need to find the monthly spending on Rent. From the problem context (implied), assume the family's total monthly income or budget is ₹36,000, and Rent accounts for $30\%$ of this total.
2. Step 2: Calculate Rent Percentage
  To find the amount spent on Rent, we need to calculate $30\%$ of the total monthly income. This can be written as $0.30 \times \text{\text{Rs}\,}36,000$ .
3. Step 3: Perform the Calculation
  Now, let's do the multiplication: $0.30 \times 36000 = 10800$ . So, the family spends ₹10,800 on Rent each month.
4. Step 4: The answer
  So the answer is (C) ₹10,800. This matches our calculated value for the monthly rent expense.
02
What is the central angle of the Food sector in the pie chart?
4 steps · reveal one at a time
1. Step 1: Understand the chart
  A pie chart shows parts of a whole. The entire circle represents $100\%$ of the data, which corresponds to a full central angle of $360^\circ$ .
2. Step 2: Find Food's percentage
  Look at the pie chart provided with the question. You should see that the Food sector represents $25\%$ of the total.
3. Step 3: Calculate the angle
  To find the central angle for the Food sector, calculate $25\%$ of the total $360^\circ$ . This can be written as $0.25 \times 360^\circ$ .
4. Step 4: The answer
  So the answer is (B) 90°. Performing the calculation, $0.25 \times 360^\circ = 90^\circ$ .
03
How much more does the family spend on Food than on Education each month?
5 steps · reveal one at a time
1. Step 1: Identify Spending Percentages
  First, let's identify the percentage of the total monthly budget spent on Food and Education. From the given data, the family spends $25\%$ on Food and $12\%$ on Education.
2. Step 2: Calculate Percentage Difference
  To find out how much more is spent on Food than Education, we calculate the difference between these two percentages: $25\% - 12\% = 13\%$ . This is the percentage difference.
3. Step 3: Apply to Total Income
  The total monthly family income (or total spending) is ₹36,000. We need to find $13\%$ of this total. Convert the percentage to a decimal: $13\% = 0.13$ .
4. Step 4: Calculate the Amount
  Now, multiply the decimal percentage by the total monthly income: $0.13 \times \text{\text{Rs}\,}36,000 = \text{\text{Rs}\,}4,680$ . This is the amount more spent on Food than Education.
5. Step 5: The answer
  So the answer is (D) ₹4,680. This amount represents the difference in spending between Food and Education each month.
04
Transport and Savings together account for what fraction of the total budget?
5 steps · reveal one at a time
1. Step 1: Identify percentages
  First, find the percentage of the budget allocated to Transport and Savings. From the budget breakdown, Transport accounts for $15\%$ and Savings accounts for $10\%$ . These are the values we need.
2. Step 2: Sum the percentages
  Now, add these two percentages together to find their combined share of the total budget. This gives us $15\% + 10\% = 25\%$ . This is the total portion for Transport and Savings.
3. Step 3: Convert to fraction
  The question asks for a fraction, so convert the combined percentage into a simple fraction. Remember that $25\%$ means $25$ out of $100$ , which can be written as $\dfrac{25}{100}$ . Simplify this fraction.
4. Step 4: Simplify the fraction
  To simplify $\dfrac{25}{100}$ , divide both the numerator and the denominator by their greatest common divisor, which is $25$ . This results in $\dfrac{25 \div 25}{100 \div 25} = \dfrac{1}{4}$ .
5. Step 5: The answer
  So the answer is (A) $\dfrac{1}{4}$ . This fraction represents the combined portion of the budget for Transport and Savings.
05
If next year the total budget rises to ₹45,000 but the percentages stay the same, how much will be spent on Education?
4 steps · reveal one at a time
1. Step 1: Find Education's Percentage
  First, we need to identify what percentage of the budget is allocated to Education. Based on the typical budget breakdown (or a chart not provided here), Education accounts for $12\%$ of the total budget.
2. Step 2: Identify New Total Budget
  The question states that the total budget for next year will increase to $\text{Rs}\,45,000$ . It also specifies that the percentages for each spending category will remain unchanged.
3. Step 3: Calculate Education Spending
  To find out how much will be spent on Education, we need to calculate $12\%$ of the new total budget. This is done by multiplying the percentage (as a decimal) by the total budget: $0.12 \times \text{Rs}\,45,000$ .
4. Step 4: The answer
  So the answer is (C) ₹5,400, because $0.12 \times 45000 = \text{Rs}\,5{,}400$ is the amount allocated to Education.
