1.      Option E

The difference between the working females in Bangalore and the working males in Chennai = 32.5 ⎯ 22.5 = 10 lakh

2.      Option B

Income per working person = Total income of city / Number of working people in city

Income per working person in Delhi = 200 Crore x 36/100  /  (30+25) Lakh = 72 / 55 = Rs.130.9
In Chennai = 200 x 16/100  /  (22.5+17.5) Lakh = Rs.80

In Mumbai = 200 x 20/100  /  (35+30) Lakh = Rs.61.53

In Kolkata = 200 x 14/100  /  (30+32.5) Lakh = Rs.44.8

In Bangalore = 200 x 10/100  /  (25+32.5) Lakh = Rs.34.78

In Jaipur = 200 x 4/100  /  (17.5+25) Lakh = Rs.18.82

The income per working person in Jaipur is the minimum.

3.      Option D

Average number of working males = 1/6 × (30 + 22.5 + 35 + 30 + 25 + 17.5) = 26.66 lakh
Average number of working females = 1/6 × (25 + 17.5 + 30 + 32.5 + 32.5 + 25) =27.08 lakh
So, required sum = 26.66 + 27.08 = 53.75 lakh

4.      Option A
Total income of Delhi = [200 ×36/100] = Rs.72 Crore
Income per person = 72 Crore / 55 Lakh = Rs.130.9
So, required difference of income = 5 lakh × 130.9 = Rs.654.5 lakh
= Rs.6.545 Crore

5.      Option C

Required % = 30/25 × 100 = 120%

6.      Option E

Required % = 20/60 × 100 = 33.3% of electrification of villages in Tripura in the year 2014

7.      Option D

Number of villages in Assam where electrification was done in 2013 = 40
Number of villages in Manipur where electrification was done in 2013 = 50
So, required ratio = 4 : 5

8.      Option C

In Assam, the number of villages where electrification was done = 30 + 40 + 30 = 100
In Manipur = 40 + 50 + 60 = 150
In Tripura = 40 + 50 + 60 = 150
In Nagaland = 40 + 20 + 50 = 110
So, maximum electrification in both Tripura and Manipur.

9.      Option B

Total number of villages in four states where electrification was done = 100 + 150 + 150 + 110 = 510
So, cost of electrification = 7500000 × 510 = Rs.3825000000

10.  Option A

Number of villages where electrification was done in 2012 = 50 + 30 + 60 + 40 = 180
Number of villages where electrification was done in 2013 = 20 + 40 + 50 + 50 = 160
Number of villages where electrification was done in 2014 = 40 + 30 + 40 + 60 = 170
In 2012 maximum electrification work was done.
