You are right. I already find kind of reductive the over 100 questions (some with multiple correct ones and different scores) that "official institutions" IQ test contains. This one is even more a joke...
Everybody with a "real" IQ of over 120 can simply analyse every single question and with some logic ("fruits question" apart
) he will find the solution. They are quite straight forward questions, some of them with very basic mathematic (that should not be included in an IQ test, like the Pithagora's question that this test contains).
IQ test in general tend to advantage anlytical/mathematical minds and that is of ocurse not the only form of intelligence. I have a friend, that studied with me, that scored a Mensa of over 170.
That advantaged him enormously in things like analysis, algebra, physics, statistics, geometery, ... but at all in foreign languages, history, geography, philosopy, arts, ... he had a HUGE CPU but a normal sized hard disk and ram.
BTW, this is a more serious (but not absolute true of course) test for english speaking people:
