Direction: The expenses of a country for a particular year is given in Pie–Chart. Read the Pie– Chart and answer the questions.

1. The per cent of the total spending that is spent on health is

1. Expenditure on health ≡ 54°
∵ 360° ≡ 100%

 ∴ 54° ≡ 100 × 54 = 15% 360

Expenditure on health ≡ 54°
∵ 360° ≡ 100%

 ∴ 54° ≡ 100 × 54 = 15% 360

1. The per cent of excess money spent on Others than that on Sports is

1. Expenditure on others = 30% = 108°

Expenditure on others = 30% = 108°
Required per cent

 = 108 - 18 × 100 18

 = 90 × 100 = 500 % 18
