Find Julian's age**
Rob was introduced to his colleague Julian during the founder's day celebration at his company in 2016. Four years later, Rob runs into Julian during the 8th founder's day celebration on 29th February 2020.
If Julian remarks that he is only four years younger than the company's age, what is Julian's current age?
Note: It is given that founder's day is celebrated only on 29th February.
Show answer & explanation
Founder's day is celebrated exclusively on leap years (every 4 years). The 8th celebration means the company has been founded for 8 * 4 = 32 years. Julian is 4 years younger than the company, so Julian is 32 - 4 = 28 years old.
Step-by-step Derivation:
Step 1: Founder's day occurs only on 29th February, meaning it is celebrated once every 4 years.
Step 2: 8th founder's day celebration corresponds to a company age of 8 * 4 = 32 years.
Step 3: Julian is four years younger than the company: Age = 32 - 4 = 28 years.
