The answer is £16265.28
That should be correct
Answer: 70.47%
100% - 13% = 87%
19% of 87% = 16.53%
remaining percent
= 87% - 16.53%
=70.47%
Step-by-step explanation:

Seems to be that the limit to compute is

Consider an arbitrary line through the origin

, so that we rewrite the above as

The value of the limit then depends on the slope

of the line chosen, which means the limit is path-dependent and thus does not exist.
