Firstly, we have to transform CHF to $\£$ in order to work with the same currency and make the comparisson:

If $\£1=1.55CHF$

$193.75CHF\frac{\£1}{1.55CHF}$

Then:

$193.75CHF=\£125$

Now we can make the comparisons:

a) In Geneva the watch costs $193.75 CHF=\£125$ and in Manchester it costs $\£143$ .

According to this:

In Geneva the watch is cheaper

b) If we want to know by how much is cheaper, we have to substract from the expensive price the value of the cheaper price:

$\£143-\£125=\£18$

Therefore:

The watch in Geneva is $\£18$ cheaper than the same watch in Manchester.
