AboutRohit Agarwal Expertise I can answer questions related to numbers and logic easily. However I sometimes face problems when solving questions that require a lot of creative thinking. I am not good at puzzles which involve a play with words, so please don't ask me to solve such puzzles for you.
Experience I have read a couple of good books containing puzzles and can now claim to have an "expert" in this field. I have been invited to become a member of Mensa.
Organizations INDIAN INSTITUTE OF TECHNOLOGY, DELHI
Education/Credentials Currently doing Dual Degree (B.Tech M.Tech) in Electrical Engineering Department from INDIAN INSTITUTE OF TECHNOLOGY, DELHI
Awards and Honors Numerous certificates recognizing my ability in Mathematics and Logical Thinking
Question I have had particular difficulty with this problem and I hope you may help. Instead of explaining it, I have inserted the actual picture.

Answer The answer is as follows:
The solid triangle weighs 4
The solid trapezium weighs 8
The semi-solid circle weighs 7
The rectangle weighs 10
The pentagon weighs 9
The semi-solid square weighs 5
The solid oval weighs 11
I'm sure that given this information, you can easily find out the weight of the hexagon, so I'll leave it up to you.
For solving, assign each variable a shape. The form equation based on the fact that to balance perfectly, both sides of the balance should have the same weight. So, for each balance, sum up the weights on either side and equate them. You'll have 8 variables and lots of equations so solving them would not be a problem.
