If the median and the range of four numbers `{x,y,2x+y,x-y}`,Where `0ltyltxlt2y` are `10` and `28` respectively, then the mean of the number

If the median and range of four numbers {x,y,2x+y,x−y}, where 0 lt y lt x lt 2y , are 10 and 28 respectively, then the mean of the numbers is :

Let the mean and variance of four numbers 3, 7, x and y (x gt y) be 5 and 10 respectively. Then the mean of four numbers 3 + 2x, 7 + 2y, x + y and x - y is ___ _

The mean and variance of the 4 observations 3,7,x,y ("where" x gt y) is 5 and 10 respectively . the mean of the observation 4+x+y , 7+x , x+y , x-y will be

If x lt y lt 2x , the median and the mean of x, y and 2x are 27 and 33 respectively, then find the mean of x and y.

The mean and median of 10,22,26,29,34,x,42,67,70,y (in increasing order) are 42 and 35 respectively then the value of (y)/(x) is

if x
