Solutions:
1. D) The number of candidates appeared from Gwalior zone in 1997 and 2000 together = 11432 + 12030 =23462.
Number of candidates appeared from Bhubaneswar zone in 1996 and 1999 together = 22899 + 23698 = 46597.
So the required percentage = 46597- 23462 / 46597 — 100 = 50%.
2. E) There is no continuous increase in numbers
3. C) Total number of appeared candidates in 1998 = 24380 and qualifying students = 500
No. of boys qualified in 1998 = [(500 / 7 + 3)] —7 = 350
No. of girls qualified in 1998 = 500 – 350 = 150
No. of boys appeared in 1998 = [(24380 / 3 + 2)] —3 = 14628
No of girls appeared in 1998 = 24380 -14628 = 9752
Required ratio = 350 / 9752 = 1/28
4. A) Total number of qualifying candidates in 1998 = 650 + 560 +510 + 500 + 220 + 490 = 2930.
Total number of qualifying candidates in 2000 = 648 + 612 + 588 + 580 + 238 + 534 = 3200.
So, the required percentage = (3200 – 2930)/3200 — 100 = 8.43%.
5. E) Qualifying percentage from Gwalior in the given years is following:
For year 1995: (130/10089) x 100 = 1.28%
For year 1996: (160/11032) x 100 = 1.45%
For year 1997: (190/11432) x 100 = 1.662%
For year 1998: (220/11987) x 100 = 1.83%
For year 1999: (240/12089) x 100 = 1.98%
For year 2000: (238/12030) x 100 = 1.97%
(6 – 10): Total number of employees = 2400
Number of male employees = 5/8 × 2400 = 1500
No. of female employees = 2400 – 1500 = 900
No. of males in HR department = 12 × 1500/100 = 180
No. of females in HR department = 11/6 × 180 = 330
No. of females in Accounts department = (1500 – 180 – 185 – 630 – 330) = 175
No. of females in IT department = 1/9 × 900 = 100
No. of males in IT department = 285 – 100 = 185
No. of males in Production department = 42/100 × 1500 = 630
No. of females in Production department = 10/100 × 630 = 63
No. of males in Marketing department = 22/100 × 1500 = 330
Number of females in Marketing department = (900 – 330 – 216 – 100 – 63) = 191
Number of males in Account Department = (1500 – 180 – 185 – 630 – 330) = 175
6. B) Required percentage = 185/1500 × 100 ≈ 12%
7. E) Number of males in Account department = 175
8. B) Required percentage = (175 + 216)/2400 × 100 = 16.29%
9. A) Required percentage = 63/100 × 100 = 7
10. D) Number of females in HR and Marketing department = 330 + 191 = 521
11. E) Required % = 20/60 × 100 = 33.3% of electrification of villages in Tripura in the year 2014
12. 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
13. 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
14. 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
15. 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.
