  15. The suspect who weighs 95 kg does not have black hair.

Question:

Using these deductions, how was Sherlock Holmes able to find the killer?

Detailed Solution

D is the killer. How? Let’s examine the clues again. Since there were 5 suspects, and each of them had different weight, shoe, umbrella, car and hair, we can start by forming a table to sort the given data:-
  • We can exclude A, as he is the victim
weight shoe umbrella car hair
B 110kg(#9)
C 90kg(#3) orange(#4)
D pink(#7)
E brown(#14)
F black(#8)
  • From deduction number #12 #11 and #5. We can say that the killer, who has a blue car, was wearing purple shoes, weighs 95kg and does not have black hair.
  • From the table we know that:
    • C has an orange car so C is cleared.
    • E was wearing brown shoes so E is cleared
    • B weighs 110 kg so B is cleared
    • F has black hair so F is cleared.
    • All this leaves D, therefore we can conclude that D is the killer.
