      1 .    
      Answer : Option B
      Explanation :
      The population of Company A above  Povertv  line = 90 x $18.5\over 100$x $36\over 100$ = 5.994 crore

      2 .    
      Answer : Option D
      Explanation :
      Difference = 90 x $12.5\over 100$ x $(72 - 28)\over 100$ = $90 \times 12.5 \times 44\over 10000$ = 4.95 crore
      3 .    
      Answer : Option D
      Explanation :
      $90\over 100 \times 100$ { 18.5 × 64 + 8 × 70 + 15 × 60 + 12.5 × 72 + 17 × 50 + 29 × 56}

      = $90\over 10000$ x {1184 + 560 + 900 + 900 + 850 + 1624}

      = $9 x 6018 \over 1000$ = 54.162 crore
      4 .

      Explanation :
      Population of Company C above poverty line = 90 x $15\over 100$ x $40\over 100$

      Population of Company D below poverty line = 90 x $12.5\over 100$ x $72\over 100$

      Ratio = $15 \times 40\over 12.5 \times 72$ = $600\over 900$ = $2\over 3$ = 2 : 3
      5 .    
      Answer : Option A
      Explanation :
      Population of Company B above poverty line = 90 x $8\over 100$ x $30\over 100$ = 2.16 crore

      Population of Company E below poverty line = 90 x $17\over 100$ x $50\over 100$ = 7.65 crore

      Reqd % = $2.16 \over 7.65$ x 100 = 28.23 $\cong$ 28 %

      = 9000 × {4 + 9 + 5 + 7 + 3 + 10}

      = 9000 × 38

      = 342000

      Average = $342000\over 6$ = 57000
