Q4 of 37 Page 195

x varies directly with y and inversely with z. When y=5, z=9 then Let us find the relation among three variables x, y and z and if y = 6 and let us write by calculating the value of x.

Given:


Acc. To given values y = 5, z = 9 and x = 1/6,





So, …(1)


Put y = 6 and z = 1/5 in (1)




⇒ x = 9

y varies directly with square root of x and y = 9 when x = 9. Let us find the value of x when y = 6.

 4

x varies directly with y and inversely with z. When y=4, z=5, then x=3. Again, if y=16, z = 30, let us write by calculating the value of x.

 5

If x ∝ y, let us show that x + y ∝ x – y.

let us show that A ∝ B.
