Its either W.H.O.'s Math SUX or I'm Retard

OK, this is the third straight entry regarding about WHO and I know all of you must be really fed up reading this. Too bad, I just can't help it!

Quoted from WHO Report again and this time, it's Malaysia's turn.

The population of Malaysia was 26.6 million in 2006, with about 42% below 20 years of age and about 67% above 60 years. The...

...The economically productive or working-age population, classified as persons aged 15 to 64 years, accounts for a sizable population of 16 million, or 63.3% of the total population...

....................................

Population below 20 years old = 42%
Population above 60 years old = 67%

and that means...
Population between 20 to 60 years old = -9%
But given that,
Population between 15 to 64 years old = 63.3%

Can you solve this?

tick tock tick tock

After having a deep thought, I shouted:

Eeeewreka!! The solution must be an imaginary number!

Calculation is done based on the assumption that population includes Malaysia Ministry of Imaginary Creatures registered ghosts! Those straying on streets, fighting on the roof tops, sleeping under your bed, everywhere within the physical boundary of Malaysia - GOOD Assumption. I am so proud of myself =)
