Case Interview Question:

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?

Submitted by: Muhammad

Use simple algebra. Say cost of chicken = x, then cost of salmon is 2x and cost of turkey is 4x
Therefore total cost = x + 2x + 4x = 7x
7x = 21 Euros
Therefore x = 3 Euros
Turkey costs 4x which is 12 Euros
