You spend 21 Euros on meat in a supermarket. You buy a turkey, a chicken and a salmon. The salmon costs half the cost of the turkey and the chicken costs half as much as the salmon. How much did the turkey cost?	Suppose I spend a third of my money on a guitar, half the rest on a microphone and a quarter of what I then have left on a kazoo. What proportion of my original money do I have left?
