Question

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

Hint:

Since incomes are equal, compare the leftover percentage, that is 100% minus Investments, for each person.

Answer 1

The Correct Option is C

Step 1: Set up equal income.
Let the income of both Balu and Paul be Rs. X, since both earn the same amount.
Each person spends 100% of income across the six heads shown in the chart.

Step 2: Find the share spent on all heads except Investments.
Balu's Investments share is 24%, so Balu spends (100 minus 24) equals 76% of X on the rest.
Paul's Investments share is 23%, so Paul spends (100 minus 23) equals 77% of X on the rest.

Step 3: Compute the difference between the two remainders.
Subtract Balu's remainder from Paul's remainder: 77% of X minus 76% of X.
This equals 1% of X, which is written as 0.01 times X.

Final Answer:
The difference in their expenditure on all heads except Investments is 0.01 of income. \[ \boxed{0.01X} \]
