Question

A shop offers the following conversions between pounds (£) and US dollars ($) : £1=$1.28 $1= £0.74 if Niamh converts £150 into US dollars and then back into pounds, what percentage of her money will she lose? Give your answer to 1 d.p.

Answer 1

Answer:5.3%

Explanation:

we say 150/1 multiplied by 0.74/1=$111

then when we convert it back to pounds, we say 111/1 multiplied by 1.28/1 =142.08

150.00-142.08=7.92

7.92/150.00 multiplied by 100=5.28 to 1 decimal place is 5.3%
