Mean = 17
\(B=-5, -1, 12 ,29,x,y\)
17 = \(\frac{-5-1+12+29+x+y}{6}\)
\(x + y = 67\)
We will not get the values of x & y from this.
Answer D
\(B=-5, -1, 12 ,29,x,y\)
17 = \(\frac{-5-1+12+29+x+y}{6}\)
\(x + y = 67\)
We will not get the values of x & y from this.

\(\frac{{(-5) + (-1) + 12 + 29 + x + y}}{6} = 17\)
\(35 + x + y = 102\)
\(x + y = 67\)
We have \(2\) variables and a single equation, So we cannot solve this further
Hence, option D
