Explanation

Sum of Post II: 950+1005+920+950+825 = 4650. Average = 4650/5 = 930. Sum of Post IV: 830+740+920+960+765 = 4215. Average = 4215/5 = 843. Difference = 930 - 843 = 87.

AI explanation

The total number of candidates applying for post II across all five companies is 950 + 1005 + 920 + 950 + 825 = 4650, making the average 4650 / 5 = 930. The total number of candidates applying for post IV is 830 + 740 + 920 + 960 + 765 = 4215, making the average 4215 / 5 = 843. The difference between these two averages is 930 - 843 = 87.
