The average of six numbers is `x` and the average of three of these is `y` . If the average of the remaining three is `z` , then `x=y+z` (b) `2x=y+z` (c) `x=2y+2z` (d) None of these

The average of six number is x and average of three of these is y. If the average of the remaining three is z,then

The average of six numbers is x and the average of three of these is y. If the average of the remaining three is z then,what is relation between x, y and z?

The average of x, y and z is 45. x is as much more than the average as y is less than the average. Find the value of z.

If x , y , z are three sums of money such that y is the simple interest on x , z is the simple interest on y for the same time and at the same rate of interest, then we have x^2=y z (b) y^2=x z (c) z^2=x y (d) x y z=1

The image of plane 2x-y+z=2 in the plane mirror x+2y-z=3 is (a) x+7y-4x+5=0 (b) 3x+4y-5z+9=0( c) 7x-y+2z-9=0 (d) None of these
