Show Answer

Answer:

Correct Answer: D

Solution:

  • Average number of candidates applying for Post II across various companies, $ =\frac{1}{5}[950+1005+920+950+825] $ $ =\frac{1}{5}\times 4650=930 $ Average number of candidates applying for Post IV $ =\frac{1}{5}[830+740+920+960+765] $ $ =\frac{1}{5}\times 4215=843 $ Hence, required difference $ =930-843=87 $
