Tweet

I'm supposed to be setting a few multiple choice questions related to IQ and Mental Aptitude and I have run out of ideas. I need about 10 more questions with answers for Class XII students. You know - the questions about what number comes next, complete the series, associations etc etc. The ones I found on the internet have no answers. So please post some Questions with the answers to help me out. I need to submit these in a few hours.
