Question

Directions: The pie chart shows the percentage of monthly expenditure of Paul and Balu across six heads - Rent, Investments, Food, Travel, Clothing and Medical.

If Paul's income was Rs. 13,500, what would be his average expenditure on Investments, Rent and Travelling?

• A. Rs. 2540
• B. Rs. 2125
• C. Rs. 2490
• D. Rs. 2650
• E. Rs. 2700

Hint:

Add Paul's percentage shares for Investments, Rent and Travel, apply that combined percentage to Rs. 13,500, then divide by 3.

Answer 1

Answer: (E)

From the outer ring of the pie chart (Paul's ring), read off the three shares needed:
Rent = 22%, Investments = 23%, Travel = 15%.

Add these three percentages first: 22% + 23% + 15% = 60% of Paul's income.

Paul's income is Rs. 13,500, so the combined amount spent on these three heads is \(60\% \text{ of } 13500 = \dfrac{60}{100}\times 13500 = 8100\).

The question asks for the average of the three expenditures, so divide this total by 3: \(\dfrac{8100}{3} = 2700\).

So Paul's average monthly expenditure on Investments, Rent and Travelling is Rs. 2700, which is option (e).
