Supposed y varies jointly with x and z. If y=20 when x=2 and z =5, find y when x=14 and z=8

Given:

The variable, y varies jointly with x and z.

It is given that, y = 20 when x = 2 and z = 5.

To find: Find y when x = 14 and z = 8

Explanation:

Since the variable y varies jointly with x and z.

So let us frame the equation as follows,

Substituting y = 20, x = 2 and z = 5 in the above equation. We get,

Substitute k = 2, x = 14, and z = 8 in equation (1), we get

Final The value of y is 224.
