Question

The mortality in a town during 4 quarters of a year due to various causes is given below: Based on this data, the percentage increase in mortality in the third quarter is

  1. 40    
  2. 50    
  3. 60    
  4. 75    

The correct answer is: 60


    Required percentage equals fraction numerator 400 minus 250 over denominator 250 end fraction cross times 100
    equals fraction numerator 150 over denominator 250 end fraction cross times 100 equals 60 percent sign.
