The ages of Ambrose, Brandon and Chester can be related to the diagram above so that when just one digit is written in each box:

- A across is Ambrose's age in years.
- A down is the sum of Ambrose's and Brandon's age in years.
- B across is the sum of Ambrose's age, Brandon's age and Chester's age
in years.
- Two of Ambrose, Brandon and Chester are the same age in years.

Who is a different age in years from the other two?

**B is the odd one =any non-zero one-digit number of yearS**

**A=C= TEN OR TWENTY OR THIRTY OR FORTY**

**SO:**

**4*9=36**

**THIRTY SIX POSSIBLE TRIPLETS (A,B,C)**

**IN mY PREVIOUS POST B & C SHOULD BE INTERCHANGED**
