Solutions:
(1 – 5): 1. C) Reqd ratio = [(350 – 90) + (760 – 294)] / [(180 – 51) + (280 – 104)]
= (260 + 466) / (129 + 176) = 726 / 305 = 726 : 305
2. B) Total villages = 750 + 700 + 1400 + 425 + 520 + 570 = 4365
3. E) Reqd difference = 140 – 104 = 36
4. B) Total number of female children = 525
5. A) Total number of adult females
P= 400 – 135 = 265
Q = 360 – 35 = 325
R = 640 – 196 = 444
S = 245 – 17 = 228
T = 240 – 104 = 136
U = 270 – 38 = 232
Total = 1630
Reqd ratio = 1630 / 525 = 326 / 105 = 326 : 105
6. C) Total Students of all colleges in 2007 =(500+480+600+490) = 2070
Number of  Students who were selected for jobs in that year=(230+250+330+280)=1090
Reqd%=(1090 / 2070) × 100=52.65%
In 2008,
Total number of  Students in all colleges=(550+450+450+520)=1970
Number of  Students who were selected forjobs=(140+310+170+170)=790
Percentage=(790 / 1970) × 100 = 40.1%
In ,2009, Total number of students in all colleges=525+590+580+590=2285
Number of  Students who were selected forjobs in 2009=(190+230+320)=1060
Percentage =(1060 / 2285) × 100 = 46.4%
In 2010 ,Total number of  Students in all colleges=(600+540+670+410)=2220
Number of  Students who were selected forjobs=(230+190+200+270)=890
Percentage= (890 / 2220) × 100 = 40.09%
In 2011,Total number of  Students in all colleges=(575+490+540+630)=2235
Number of  Students who were selected forjobs=(210+310+180+200)=900
Percentage= (900 / 2235) × 100=40.26% In 2012,
Total number of  Students in all colleges=(580+500+700+650)=2430
Number of  Students who were selected forjobs=(220+200+250+310)=980
Percentage= (980 / 2430) ×100=40.32%
In 2007, Percentage of  Students who were selected for jobs was the maximum
7. A) Total  Students of college C during 2007 – 2012=(600+450+580+670+540+700+=3540
No.of Students selected for jobs in college C during 2007- 2012=(330+170+320+200+180+250)=1450
Required ratio=3540:1450=354:145
8. B) Total No.of  Students college A in 2009=525
No.of Students selected for jobs=190
Percentage of  Students who got jobs = (190 / 525) × 100=36.19%
Total No.of  Students college B in 2009=590
No.of Students selected for jobs=230
Percentage of  Students who got jobs = (230 / 590) × 100=38.98%
Total No.of  Students college in 2009=580
Those selected for jobs=320
Percentage of  Students who got jobs = (320 / 580) × 100=55.17%
Total  Students college D in 2009=590
Those  who selected for jobs=320
Percentage of  Students who got jobs =320/590 x 100=54.23%
Required college is C.
9. D) Total  number of Students college D  who were selected for jobs during 2007-2012=(280+170+320+270+200+310+=1550
Total  number of Students of college B who were selected for jobs during 2007-2012=(250+310+230=190+310+200)=1490
Required  Percentage= [(1550 – 1490) / 1490] × 100=60 = (60 / 1490 )100=4.02%
10. D) Let the CP of a hen and a goat  be Rs. x and Rs. y respectively.
Then, (5x / 4) + (6y / 5) = 540 or 25x + 24y = 10800                   ……(i)
Again,  (6x / 5) + (5x / 4) = 538 or 24x  + 25y = 10760                …….(ii)
Solving we get x = Rs. 240                 y = Rs. 200
(11 – 15): City Age above 40 years Age below 40 years P 220 305 Q 377 290 R 400 267 S 220 330 T 320 480 U 267 356 Total 1804 2028
11. B) Total number of people whose age is below 40 years = 2028
12. D) Number of people below 40 years from city P = 305,
Number of people above 40 years from city P = 220
Required Ratio = 305 : 220 = 61 : 44
13. C) Total number of people below 40 year of age = 2028,
Total number of people below 40 year of age who are from R = 267,
Required Percentage = 267*100/2028 = 13.16%
14. A) No. of people from city T who are above 40 years of age = 320
No. of people from city T who are below 40 years of age = 480
No. of males above 40 years of age = 320 × 0.45 = 144
Total no. of males from city T = 800 × 0.65 = 520
No. of males from city T who are below 40 years of age in city T = 520 – 144 = 376
No. of females below 40 years of age in city T = 480 – 376 = 104
15. B) Total number of people below 40 year of age = 2028,
Total number of people above 40 year of age = 1804
Therefore required percentage = 12.42%.
