Detailed Solution

Given x and y vary inversely and x = 32, where y = 9.
We need to find x when y = 48.
Using the fact that multiplication of x and y is constant if they are in inverse proportion.

48 x = 9 \times 32

x = \frac{9 \times 32}{48}

x = \frac{3 \times 32}{16}

x = 3 \times 2

x = 6

Value of x is 6.
Hence, the correct option is 1.
