Without taking an official IQ test, is there any way to guess what one’s IQ might be? by Yong Jia Hui
Answer by Yong Jia Hui:
Yes, Simply answer these 3 questions:
1) A bat and a ball cost $1.10 in total. The bat costs $1.00 more than the ball. How much does the ball cost?
2) If it takes 5 machines 5 minutes to make 5 widgets, how long would it take 100 machines to make 100 widgets?
3) In a lake, there is a Patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake? 
Are you ready for the answers?
It’s not surprising then that only 48 percent of MIT students were able to answer all three questions correctly.
This should give you a somewhat accurate estimate of your intelligence level, since the test has been found to have a substantial correlation with cognitive ability and is potent predictor of performance on a wide sample of tasks.
I have done a iq test some years back, and turns out, I have a high average to superior intellect. I got 2 questions correct.
So now you can roughly gauge your own intelligence level
Hope this helps
EDIT: in case you have mistaken, this test isn’t official and is nowhere as accurate as official ones due to its lack of question variety. It is vague as a comparison between you and the MIT students’ result is needed to determine whether you’re above average.
