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?

If the average of x, y, and z is 32 and the average of y and z is 27. What is the average of x and 2x?

The average of x, y and z is 8 and the average age of y and z is 4. What is the value of x?

The average of w, x, y, and z is 31. If the average of w and y is 24, what is the average of x and z?

The averge of x and 3y is 12, the average of 2x and 3z is 21. What is the average of x,y and z ?

If the average of x, y, and z is 12, what is the average of 3x, 3y, and 3z?

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
