Question 2

A pie chart shows how a household spends its income: Housing 35%, Food 25%, Transport 15%, Savings 10%, Other 15%. If monthly income is $4,000, how much is spent on food and transport combined?

A bar chart displays the number of cars sold by four dealerships: A=120, B=95, C=150, D=135. What percentage of total sales did dealership C achieve?

Accepted Answer

37.5%

Total = 500; C's share = 150/500 × 100 = 30%... wait, 150/500=0.30=30%. Let me recompute: 120+95+150+135=500, 150/500=30%.
