Shaan is 333 times as old as christopher and is also 141414 years older than christopher.
how old is christopher?

First, let's assign variables to these uncomfortably old people:

s = Shaan's age

c = Cristopher's age

The question gives us two equations,

s = 333c

and

s = 141414+c

We can input s = 141414+c into the first equation to replace s.

141414+c = 333c

Subtract both sides by c:

141414 = 332c

Divide:

141414/332 = c

c = 425

c = 425 years old
