So Horse1 has odds of 4.5 and horse2 has odds of 7.6 and I have a target profit of £20 if either of these horses win. I do have a dutch calculator to give me the figures, but the author will not reveal the maths to me and I am sure it must be simple. Now i know that I need to stake £6.88 on horse1 and £4.07 on horse2.

Horse1 odds = 4.5, stake = £6.88 - if wins, gain £24.08

Horse2 odds = 7.6, stake = £4.07 - if wins, gain £26.86

If horse1 wins, profit = £24.08 - £4.07 = £20.01

If horse2 wins, profit = £26.86 - £6.88 = £19.98

so what I need here is the maths for working out the stakes - can anybody help please? Many thanks.
