Answer 1

those in consulting exceed *by* 36 not 72

Answer 2

Answer:

3. 108

Explanation:

Consulting % = (72/360) * 100 = 20%

Software % = (36/360) * 100 = 10%

Manufacturing % = (54/360) * 100 = 15%

Let, the total number of students be x

0.2x - 0.1x = 72

x = 720

Manufacturing students = 1`5% of 720 = 108

Answer = 108
