In 2022, State Q allocated 35% of the budget for girls. In 2023, this budget allocation for girls was proposed to be increased by 35% of the allocation for girls in 2022. With no other change, what is the percent increase in budget allocation for 2023 with reference to 2022?

The correct answer is

12.25%

Budget Allocation Analysis for State Q

The question asks us to analyze the budget allocation for education in State Q, specifically focusing on the year 2022 and a proposed change for 2023 related to the budget for girls.

Let's first look at the provided table showing the budget allocations:

Year-wise Budget Allocation (in Rs. crore)
Year State P State Q State R
2018 200 270 330
2019 250 314 374
2020 264 296 344
2021 410 346 384
2022 430 364 440

Understanding State Q's Budget Allocation

From the table, we can see the total budget allocation for State Q in 2022 is Rs. 364 crore.

The question provides additional information about how this budget is allocated within State Q:

  • In 2022, 35% of State Q's budget was allocated for girls.
  • In 2023, the budget allocation for girls was proposed to increase by 35% of the 2022 allocation for girls.
  • No other change occurred in the budget allocation.

Step-by-Step Calculation of Percent Increase

We need to find the percent increase in the total budget allocation for State Q in 2023 compared to 2022. Since the only change is the increase in the budget for girls, this increase in the girls' budget is the total increase in the State Q budget for 2023.

Step 1: Find the total budget for State Q in 2022.

From the table, Total Budget for State Q in 2022 = Rs. 364 crore.

\( \text{Total Budget}_{2022, Q} = 364 \text{ crore} \)

Step 2: Calculate the budget allocated for girls in State Q in 2022.

Budget for girls in 2022 was 35% of the total budget in 2022.

\( \text{Budget for girls}_{2022, Q} = 35\% \text{ of } 364 \)

\( \text{Budget for girls}_{2022, Q} = \frac{35}{100} \times 364 \)

\( \text{Budget for girls}_{2022, Q} = 0.35 \times 364 \)

Step 3: Calculate the proposed increase in the budget for girls in 2023.

The increase was 35% of the allocation for girls in 2022.

\( \text{Increase in budget for girls}_{2023, Q} = 35\% \text{ of } (\text{Budget for girls}_{2022, Q}) \)

\( \text{Increase in budget for girls}_{2023, Q} = \frac{35}{100} \times (0.35 \times 364) \)

\( \text{Increase in budget for girls}_{2023, Q} = 0.35 \times 0.35 \times 364 \)

\( \text{Increase in budget for girls}_{2023, Q} = (0.35)^2 \times 364 \)

\( \text{Increase in budget for girls}_{2023, Q} = 0.1225 \times 364 \)

Step 4: Determine the total increase in budget allocation for State Q in 2023.

Since there were no other changes, the total increase in State Q's budget in 2023 compared to 2022 is exactly the increase in the budget for girls.

\( \text{Total Increase}_{2023 \text{ vs } 2022, Q} = \text{Increase in budget for girls}_{2023, Q} \)

\( \text{Total Increase}_{2023 \text{ vs } 2022, Q} = 0.1225 \times 364 \)

Step 5: Calculate the percent increase in total budget allocation for 2023 with reference to 2022.

The percent increase is calculated as: \( \frac{\text{Total Increase}}{\text{Original Budget}} \times 100 \).

Original Budget (reference) is the total budget in 2022, which is 364.

\( \text{Percent Increase} = \frac{0.1225 \times 364}{364} \times 100 \)

The term 364 cancels out:

\( \text{Percent Increase} = 0.1225 \times 100 \)

\( \text{Percent Increase} = 12.25 \)

So, the percent increase in budget allocation for 2023 with reference to 2022 is 12.25%.

Revision Table: Key Concepts

Concept Explanation Formula Example
Percentage A fraction of 100, represented by the symbol %. Used to express a part of a whole. \( 35\% = \frac{35}{100} = 0.35 \)
Calculating a Percentage of a Value To find \( X\% \) of a value \( V \), multiply \( V \) by \( \frac{X}{100} \) or \( X/100 \). \( 35\% \text{ of } 364 = 0.35 \times 364 \)
Calculating Percent Increase Compares the amount of increase to the original value and expresses it as a percentage. \( \text{Percent Increase} = \frac{\text{Amount of Increase}}{\text{Original Value}} \times 100\% \)

Additional Information: Data Interpretation Tips

When solving data interpretation problems involving tables and percentages, consider the following tips:

  • Read the question carefully to understand exactly what is being asked. Identify the specific years, states, or categories involved.
  • Note down the key numbers directly from the table that are relevant to the question.
  • Break down percentage calculations step-by-step. Calculate intermediate values if necessary (like the budget for girls in 2022).
  • Pay close attention to what the percentage is "of". For example, is the increase 35% of the original total budget, or 35% of a specific part of the budget?
  • Understand the reference point for percent change (e.g., percent increase with reference to 2022 means the 2022 value is the denominator).
  • Keep track of the units (e.g., Rs. crore, percentage).
  • Simplify calculations where possible, as shown in the step where 364 cancelled out.
