Question

Study the given pie chart carefully and answer the question that follows.
The pie chart below shows the percentage of monthly expenditures of Paul and Balu, split across Rent, Investments, Food, Travel, Clothing and Medical.

If both Balu and Paul get equal income, what would be the difference of their expenditures on all categories except Investments?

• A. Rs. 1 of income
• B. Rs. 0.50 of income
• C. Rs. 0.01 of income
• D. Rs. 0.05 of income
• E. Rs. 2 of income

Hint:

Subtract each person's Investments % from 100% to get their combined spend on the rest, then find the difference between the two.

Answer 1

The Correct Option is C

The six categories in the chart always add up to 100% for each person, so the total spent on all categories except Investments is simply \(100\% - \text{Investments}\%\).

Step 1: Find Balu's expenditure on all categories except Investments.
Balu's Investments \(= 24\%\), so the rest \(= 100\% - 24\% = 76\%\)

Step 2: Find Paul's expenditure on all categories except Investments.
Paul's Investments \(= 23\%\), so the rest \(= 100\% - 23\% = 77\%\)

Step 3: Since both have equal income, the difference between the two is the difference of these percentages, applied to the common income.
\[77\% - 76\% = 1\% \text{ of income} = 0.01 \times \text{income}\]

So the difference between their expenditures on all categories except Investments is Rs. 0.01 of income, option (c).
