In Company B, the difference between the number of Arts graduate employees and Science graduate employees is
A174
B178
C154 ✓ Correct
D146
Correct answer: (C) 154
Explanation
The difference is 154, so the answer is 154.
Company B has 1400 employees with 31 percent Commerce and 40 percent Arts graduates.
So the Science graduates are 100 minus 31 minus 40, which is 29 percent.
That is 1400 times 29 over 100, which is 406 Science graduates.
The Arts graduates are 40 percent of 1400, which is 560.
The difference is 560 minus 406.
That equals 154.
