The trick to solving this problem is realising that you are dealing with hourglasses which can be reversed. The following solution would not be possible with other time measuring devices: Time = 0: Set T7 and T4, start cooking the egg. Time = 4: T7 has 3 left, re-set T4, egg is 4 min cooked Time = 7: Re-set T7, T4 has 1 left, egg is 7 min cooked Time = 8: T4 runs out; T7 has 6 left. Rotate it. It now has 1 left. Egg is 8 min cooked Time = 9: T7 runs out, egg is fully cooked.
