Question

Toby goes on holiday to Geneva, Switzerland. In Geneva, Toby sees a watch costing 193.75 CHF (swiss france). In Manchester, an identical watch costs 145 pounds. Given that 1 pound= 1.55 CHF

Answer 1

Part a) In Geneva the watch is cheaper

Part b) The watch in Geneva is
`\£20` cheaper than the same watch in Manchester

Explanation:

The question is

a) In which city is the watch cheaper?

b) By how much is it cheaper (in £)?

Part a)

Transform
`CHF\ to\ \£` in order to work with the same currency and make the comparison

If
`\£1=1.55CHF`

`193.75\ CHF=193.75((1)/(1.55))=\£125`

Now we can make the comparisons:

In Geneva the watch costs

`\£125`

and

in Manchester it costs

`\£145`

`\£125 < \£145`

therefore

In Geneva the watch is cheaper

Part b)

If we want to know by how much is cheaper, subtract from the expensive price the value of the cheaper price

`\£145-\£125=\£20`

Therefore

The watch in Geneva is
`\£20` cheaper than the same watch in Manchester
