Study the following table carefully and answer the questions given below :
Number of Candidates Applying for Various Posts Across Various Companies
What is the difference between the average number of candidates applying for Post II and the average number of candidates applying for Post IV across various Companies?
Number of candidates applying for Post II across various Companies
= 950 + 1005 + 920 + 950 + 825 = 4650
Number of candidates applying for Post IV across various Companies
= 830 + 740 + 920 + 960 + 765 = 4215
=> Required difference = 4650 - 4215 = 435
=> Required average = $$\frac{435}{5} = 87$$
