(Q.no: 1-5). Refer to the table and answer the given questions.
Total Population in Five Cities = 20,00,000

1. The total population of City A and C is 7,55,000. The difference between the total population of City A and C is is 1.25 lakhs. If the City C has more population than City A then the urban population of City A and C together is approximately what percent of total population of these two Cities?
   A. 39%
   B. 12%
   C. 13%
   D. 11%
   E. None of the Above
   
   Answer & Explanation

   Answer – A. 39%
   Explanation :
   A + C = 7,55,000
   (C has more population than A) C – A = 125000
   C = 4,40,000 ; A = 315000
   Urban population of City A and C = 3/10 * 315000 + 5/11 * 440000 = 294500
   % = (294500 / 755000)*100 = 39%
   
   
2. The difference between the number of male and female in the City A is 15000. Approximately, by what percent of urban population of City A less than its Rural population?
   A. 75%
   B. 57%
   C. 55%
   D. 68%
   E. None of the Above
   
   Answer & Explanation

   Answer – B. 57%
   Explanation :
   X= Total population in City A
   1/21 * x = 15000 => x = 3,15,000
   Rural Population = 2,20,500
   Urban Population =94,500
   % = (Difference / Rural Population)*100 = (1,26,000 / 2,20,500)*100 = 57%
   
   
3. One – fourth of total population of City C is 1,10,000.  If the total number of Literate graduates of City B and D are 15,570 and 91,000. What % of the total population of City B, C and D together is literate?
   A. 28.6%
   B. 17.6%
   C. 50.6%
   D. 25.6%
   E. 45.6%
   
   Answer & Explanation

   Answer – C. 50.6%
   Explanation :
   1/4 * C = 1,10,000 => C = 4,40,000
   Literate population of City C  = 7/11 * 4,40,000 = 2,80,000
   Total number of Literate graduates of City B = 15570 = 45%
   x = Literate population of City B
   45% of x = 15570 => x = 34600
   Total number of Literate graduates of City D = 91000 = 65%
   y = Literate population of City D
   65% of y = 91000 => x = 280000
   % = (594600/1175000) * 100 = 50.6%
   
   
4. The difference between the total population of City C and E is 30,000. The ratio of total population of City C and E is 44:41.  Total % of Literate graduates of City C and E is 80%. If the % Literate graduates of City E is equalled to three times of Literate graduates of City C then what is the difference between the number of graduates from City C and City E?
   A. 43800
   B. 42600
   C. 44800
   D. 45800
   E. 42400
   
   Answer & Explanation

   Answer – E. 42400
   Explanation :
   3/85 * x = 30000 => x = 85000
   44/85*85000 = 440000 = City C Population
   7/11*440000 = 280000
   Number of graduates from City C = 20% of 280000 = 56000
   41/85*85000 = 410000 = City E Population
   2/5*410000 = 164000
   Number of graduates from City E = 60% of 1,64,000 = 98400
   Difference = 42400
   
   
5. What is the sum of male population in City B and female population in City D together ?
   A. 3,76,000
   B. 3,10,500
   C. 3,60,000
   D. 3,60,500
   E. None of the Above
   
   Answer & Explanation

   Answer – B. 3,10,500
   Explanation :
   Sum = 7/11 * 315000 + 3/14 *420000 = 220500 + 90000 = 310500
   
   

(Q.no: 6 -10). Refer to the table and answer the given questions.

   B. 3:1
   C. 9:5
   D. 6:5
   E. 5:7
   
   Answer & Explanation

   Answer – B. 3:1
   Explanation :
   48% of 1000 = 480
   Valid votes of Female = 120
   Valid votes of Male = 480 – 120 = 360
   => 360:120
   => 3:1
   
   
7. The total number of votes increased by 20% from 2002 to 2006. If 25% of the votes valid in 2006, what was the number of valid votes in 2006?
   A. 205
   B. 250
   C. 150
   D. 140
   E. 130
   
   Answer & Explanation

   Answer – C. 150
   Explanation :
   20% of 500 = 100
   = 500 + 100 = 600
   25% of 600 = 150
   
   
8. If the average number of valid votes in 2002 and 2005 was 435, approximately, what percent of total votes valid in 2002?
   A. 30%
   B. 31%
   C. 54%
   D. 40%
   E. 50%
   
   Answer & Explanation

   Answer – C. 54%
   Explanation :
   Number of valid votes in 2002 and 2005 = 870
   2005: 40% of 1500 = 600
   870 – 600 = 270
   (270/500)*100 = 54%
   
   
9. In 2004, if the difference between number of valid votes of male and number of valid votes of female was 120, what was the total number of votes in 2004?
   A. 1840
   B. 1200
   C. 1660
   D. 1600
   E. 1720
   
   Answer & Explanation

   Answer – B. 1200
   Explanation :
   x = Valid Votes; y = Total Votes
   (1/6)*x = 120
   x = 720
   60% of y = 720
   y = 1200
