Solution
Total number of employees in Company N = 700
Percentage of Science graduate employees
$= [100 – (31 + 40)] = 29\%$
Now, the percentage difference between Arts graduate employees and Science graduate employees
$= (40 - 29)\% = 11\%$
$\therefore~11\% $ of 700 = 77
$\therefore~$ Difference = 77
