A) 85
B) 92
C) 83
D) 87
E) None of these
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 \[=930-843=87\] |
