That was sold for £11, £1.60 was the cost. Also, am I ring in assuming that I've made back my investment (£43 total for 10 KD's) + made an extra £45.8 (so far)?

Also let's say if at the end I've sold all 10 and made £70. Everytime if I sell and make the same amount it will always be - £43 investment returns back £70 + initial investment.
