# One algebra question

#### WMDhamnekar

Hello,

Given that w varies directly as the product of x and y and inversely as the square of z and that w = 4 when x = 2, y = 6, and z = 3. Find the value of w when x = 1, y = 4, and z = 2.

Actually i didn't understand this question. How to answer it i don't know.
Multiple choices given are as follows:-
1)3.

2)4.

3)5.

4)2.
If any member want to explain what the author meant to say, or if he/she knows the correct answer, he/she may reply with correct computation.

#### Idea

this means $$\displaystyle w=k \frac{x y}{z^2}$$ for some fixed number $$\displaystyle k$$
