Question

My neighbour has lived all over the world. I asked how old are you? He said " I lived 1/4 of my life in China, 1/6 of my life in Vietnam, 1/2 of my life in Cambodia and 22 years in Australia.
How old is he???

Answer 1

$\frac{1}{4}x+\frac{1}{6}x+\frac{1}{2}x+22=x|\cdot12\\ 3x+2x+6x+264=12x\\ x=264$

 I guess there's a mistake in the question.
