#### Data Interpretation

Direction: The pie- chart, given here, shows various expenses of a publisher in the production and sale of a book. Study the chart and answer questions based on it. 1. Miscellaneous expenses are what per cent of paper cost?

1. Required percentage

 = 4 × 100 = 40% 10

##### Correct Option: C

Required percentage

 = 4 × 100 = 40% 10

1. The measure of central angle for the section ‘printing cost’ is :

1. ∵ 100% ≡ 360°

 ∴ 35% ≡ 360 × 35 = 126° 100

##### Correct Option: A

∵ 100% ≡ 360°

 ∴ 35% ≡ 360 × 35 = 126° 100

1. If the printing cost is \$ 17,500, the ‘Royalty’ paid is :

1. ∵ 35% o 17500

 ∴ 15% ≡ 17500 × 15 = \$ 7500 35

##### Correct Option: B

∵ 35% o 17500

 ∴ 15% ≡ 17500 × 15 = \$ 7500 35

Direction: The pie- chart given here shows expenditures incurred by a family on various items and their savings, which amounts to \$ 8,000 in a month. Study the chart and answer the questions based on the pie-chart 1. How much more amount is spent on food than on housing?

1. Difference in degree of amount spent on food & housing = (120 – 105)

 = 15° 8000 × 15° = \$ 2000 60

##### Correct Option: C

Difference in degree of amount spent on food & housing = (120 – 105)

 = 15° 8000 × 15° = \$ 2000 60

1. What is the total expenditure of the family for the month?

1. Total expenditure

 = 8000 × (105 + 120 + 45 + 30) 60

 = 8000 × 300 60

##### Correct Option: A

Total expenditure

 = 8000 × (105 + 120 + 45 + 30) 60

 = 8000 × 300 60
