Step-by-step explanation:
Total number of men=24
Number of men wearing red shirt= 1/2×24=12 men
Number of men wearing green shirt= 1/3×24=8 men
So total number of men wearing a shirt other than blue= 12+8=20 men
Number of men wearing blue shirt=24-20=4 men.
Hence the answer is 4 men.
Hope this helps you :)
