Interhalogen compound is:

$$X{Y}_{n_1}+H_{2}O\to n_{1}HY+HX{O}_{n_2}$$

Given compound is polar and non-planar.

Among interhalogens:

$XY$ → linear, non-polar

$X{Y}_3$ → T-shaped, polar

$X{Y}_5$ → square pyramidal, polar and non-planar

$X{Y}_7$ → pentagonal bipyramidal, non-polar

So,

$$X{Y}_{n_1}=X{Y}_5$$

Thus,

$$n_1=5$$

Hydrolysis:

$$\boxed{X{Y}_5+3H_{2}O\to 5HY+HX{O}_3}$$

Therefore,

$$n_2=3$$

Hence,

$$n_1+n_2=5+3=\boxed{8}$$
