In A, C and F states, percentage of non-electrified villages are 25, 20 and 30 per cent respectively.

Correct Option: A

In A, C and F states, percentage of non-electrified villages are 25, 20 and 30 per cent respectively. Hence, percentages of electrified villages for these states are 75, 80 and 70 percent respectively.

Percentage of electrified villages in state D = 100 - 60
Percentage of electrified villages in state C = 100 - 20

Correct 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.

Percentage of electrified villages in the state A = 100 - 25 .

Correct Option: D

Percentage of electrified villages in the state A = 100 - 25 = 75%

∵ Area of the circle = πr²
Required Area of the rectangle = Length x Breadth

Correct Option: C

given :- Area of the circle = 616
⇒ πr² = 616
Put the value of π = 22/7 in above equation.
we will get,
⇒ r² = 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 cm²

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 million
