Mixed Quantitative Aptitude Questions Set 140

Directions(1-5): Read the following table and answer the following question :
Total number of voters in different districts and Percentage of male out of these voters are given.

1. Find the ratio of the male voters from district D and E together to the female voters form district C, E and F together?
   15:23
   17:32
   11:14
   10:13
   10:31
   Option E
   No. of male voters from district D and E = 250 × 46/100 + 300 × 45/100 = 115 + 135 = 250
   No. of female voters from C, E and F = 370 × 50/100 + 300 × 55/100 + 625 × 68/100
   = 185 + 165 + 425 = 775
   Ratio = 250:775 = 10:31
   

    

2. The no. of female voters from district F is what percent more/less than the no. of male voters from district A? (rounded off to nearest integer)
   323%
   313%
   305%
   289%
   311%
   Option C
   No. of female voters from F = 625 × 68/100 = 425
   No. of male voters from A = 350/1 × 30/100 =105
   Req.% = (425−105)/105 × 100 = 304.7% ==305%
   

    

3. Total number of male voters from district A and B together are how much more/less than total number of female voters from district E and D together?
   10
   14
   19
   21
   23
   Option D
   No. of male voters from district A and B = 30/ 100 × 350 + 54/100 × 400
   = 105 + 216 = 321
   Total no. of female voters from E and D = 250 × 54/100 + 300 × 55/100
   = 135 + 165 = 300
   Difference = 321 – 300 = 21
   

    

4. The average of total voters from district B, C and D together are approximately what percent less/more than the no. of male of voters from districts D,E and F together?
   15.25%
   24.44%
   33.33%
   17.71%
   20.15%
   Option B
   Average no. of voters from district, B, C and D = (400+370+250)/3
   Male voters from D,E, and F together = 250 × 46/100 + 300 × 45/100 + 625 × 32/100
   = 115 + 135 + 200 = 450
   Req. % = (450−340)/450 × 100 = 24.44%
   

    

5. Find the ratio of no. of male voters from districts B and E together to the no. of female voters from districts C and A together?
   343:443
   351:430
   357:440
   350:416
   313:413
   Option B
   No. of male voters from B = 400 × 54/100 =216
   No. of male voters from E = 300 × 45/100 =135
   No. of female voters from C = 370 × 50/100 =185
   No. of female voters from A = 350 × 70/100 =245
   Required ratio = 351:430
