Let x = amount of salary before raise
x + 5%x = 15750
1.05x = 15750
x = 15,000
that's it! :)

Right, you now know that 15750 is 105%.
Divide 15750 by 105, times that by 100, and you get the original amount back.

=£15750 x 100/105

Current salary is 105% of salary before rise.
Hence salary before rise is 100/105x15750=15000
