x varies inversely as square of y. Given that y=2 for x=1. The value of x for y =6 is will be equal to :

Options
- 1:7
- 1:8
- 8:1
- 9:1

CORRECT ANSWER : 9:1

Discussion Board
my answer is

x varies inversely so
x= n/(y)^2
when x=1 and y = 2

1= n/ (2)^2
1=n/4
n=4

while y=6
x=?
x=n/y^2
x=4/6^2
x=4/36
x=1/9
i think answer should be 1:9
?

..

In the question they clearly given that x varies inversely to the y, so when Y=2 then X=1 ..in the same manner if Y=3 then X=0 by this if Y=6 then X= -3 so the difference between 6&-3 is 9 so the answer is 9:1
