Question

An apple, 2 oranges and 3 pears cost £2.10 altogether. An orange and a pear cost 64 pence. How much more does an apple cost than a pear?

Answer 1

There's no single solution.
All you know is that
a+p = 82
a+o = 18
So, some solutions are
orange costs 10
apple costs 28
pear costs 54

orange costs 23
apple costs 41
pear costs 41

or a bunch of other ways. You should be able to find some where an apple costs more than a pear.
