=1760
P. O. E - 65×72
=4680

Therefore, It is not in proportion.

hope it helps !!

Answer 2

$\huge \underline \mathfrak {Solution:-}$

The numbers the said to be in proportion of product of there extreme is equal to product of mean.

Here, extreme are:- 63 and 72.

product of extreme = 63 × 72 = 4536

Mean are :- 55 and 32

product of mean = 55 × 32 = 1760

Since , Product of extreme ≠ Product of mean

So, they are not in proportion.
