Percentage of electrified villages in state D = 100  60
Percentage of electrified villages in state C = 100  20Correct Option: A
Percentage of electrified villages in state D = 100  60 = 40
Percentage of electrified villages in state C = 100  20 = 80
Hence, the percentage of electrified villages in the state C is double the percentage of electrified villages in state D.

 The area of the circle is 616 cm^{2}. What is the area of the rectangle?

View Hint View Answer Discuss in Forum
∵ Area of the circle = πr^{2}
Required Area of the rectangle = Length x BreadthCorrect Option: C
given : Area of the circle = 616
⇒ πr^{2} = 616
Put the value of π = 22/7 in above equation.
we will get,
⇒ r^{2} = 196
⇒ r = 14 cm
Length of the rectangle = Diameter of the circle = 2r
Breadth of the rectangle = Radius of the circle = r
∴ Area of the rectangle = Length x Breadth
∴ Area of the rectangle = 28 × 14 = 392 cm^{2}
 What is the average female population in million?

View Hint View Answer Discuss in Forum
Average female population = sum of total numbers of females total number of cities
Correct Option: A
From above given table , we can see that
The total population of all cities = 12 + 15 + 17 + 19 + 22 = 85 million
Total males in all cities = 6.5 + 7.2 + 9.0 + 9.9 + 10.8 = 43.4 million
Total females = 85 – 43.4 = 41.6 millionAverage female population = sum of total numbers of females total number of cities = 41.6 = 8.32 million 5
