It is gvien that y varies inversely as x.
The relation between x and y in mathematical expressin is given as.

The value of y is 11 when x is 8 , we have to determine the value of y when x is 10.
Apply the mathematical expression and substitute the value of x and y ,


Now , substitute the value of k in the mathematical expression and value of x which is 10, to find the value of y.


Thus the value of y is 8.8 when x is 10.
