Direction: Study the following pie-chart and answer the questions.

1. The difference in the amount estimated by the family on electricity and call bill is :

1. As per the given pie chart in question ,
Difference in expenditure percent on electricity and call bill = (19 – 6)% = 13%
Total salary = \$ 32000 per month
Required difference = 13% of \$ 32000

Correct Option: D

As per the given pie chart in question ,
Difference in expenditure percent on electricity and call bill = (19 – 6)% = 13%
Total salary = \$ 32000 per month
Required difference = 13% of \$ 32000

 Required difference = \$ 32000 × 13 = \$ 4160 100

1. Due to sudden marriage, the family incurs miscellaneous expenditure of \$ 3040 in total. Then the increase in the amount under this head from that budgeted is :

1. According to given pie chart in question ,
Budgetary expenditure on miscellaneous items = 7% of \$ 32000

 Budgetary expenditure on miscellaneous items = \$ 32000 × 7 = \$ 2240 100

Correct Option: D

According to given pie chart in question ,
Budgetary expenditure on miscellaneous items = 7% of \$ 32000

 Budgetary expenditure on miscellaneous items = \$ 32000 × 7 = \$ 2240 100

New expenditure = \$ 3040
∴ Increase = \$ (3040 – 2240) = \$ 800

1. The budget estimated by the family on clothing and grocery together is :

1. According to given pie chart in question ,
Expenditure percent on clothing and grocery = (8 + 20)% = 28%
Total salary = \$ 32000 per month
∵ 100% ≡ \$ 32000

 ∴ 1% = \$ 32000 100

Correct Option: B

According to given pie chart in question ,
Expenditure percent on clothing and grocery = (8 + 20)% = 28%
Total salary = \$ 32000 per month
∵ 100% ≡ \$ 32000

 ∴ 1% = \$ 32000 100

 ∴ 28% ≡ \$ 32000 × 28 = \$ 8960 100

Direction: In the given pie-chart, the comparative study of the production of Rice, Wheat, Sugar and Tea of a country is given. Study the pie-chart and answer the following questions.

1. The total production of rice, wheat, sugar and tea (in kgs) is 500000 kgs. The production of rice in the country is

1. On the basis of given pie chart in question ,
Total production = 500000 kg
Production percentage of rice = 55%
Production of rice = 55% of 500000 kg

Correct Option: C

On the basis of given pie chart in question ,
Total production = 500000 kg
Production percentage of rice = 55%
Production of rice = 55% of 500000 kg

 ∴ Production of rice = 500000 × 55 = 275000 kg. 100

1. The central angle of percentage of wheat is

1. As per the given pie chart in question ,
Production percentage of wheat = 30%
The corresponding angle of total production of food grains = 360°
∵ 100% ≡ 360°

 ∴ 1% = 360° 100

Correct Option: D

As per the given pie chart in question ,
Production percentage of wheat = 30%
The corresponding angle of total production of food grains = 360°
∵ 100% ≡ 360°

 ∴ 1% = 360° 100

 ∴ 30% ≡ 360° × 30 = 108° 100
