Mean = sum of the numbers/total numbers


Mean = \frac{35 + 17 + 22 + 26+ 29 + 34 + x + 42 + 67 + 70 + y}{11}


So 42 = \frac{342 + x + y}{11}


\Rightarrow x + y = 462 - 342 = 120. Assume this to be equation 1.


The number of terms is 10, so the median will be the average of the n^{th} and \frac{n+1}{2}^{th} term or the 5^{th} and the 6^{th} term.

Median = 35, so \frac{34 + x}{2} = 35


Solve for x to get x = 36


Plug this back in equation 1 and solve for y to get y = 120 - 36 = 84


So, x and y are 36, 84.
