A typical sample GEP Exam Paper Question (Math) is the Chicken and Rabbit Question. This test is highly popular in the GEP Screening / GEP Selection Test, Round 1 or even extremely difficult Round 2.
A sample question would go like this:
A farmer has 36 chickens and rabbits in total.
He counted 124 legs altogether.
How many chickens and how many rabbits are there?
(By the way, this question is generated from my Chicken and Rabbit Question Generator!)
This is a highly typical GEP Exam paper question that may come out in the GEP test.
How do we solve it? One way is the trial and error or Guess and Check method. However, this method may not work for high numbers. What if the farmer had 10000 sheep?
The GEP Exam Paper has limited time, hence, we would need to solve it in an efficient way.
There is one method called the Assumption method, where students can remember the acronym ASSD!
Steps of ASSD to solve GEP Exam Paper “Chicken and Rabbit” Question:
Step 1 (A): Assume) Let’s assume all the 36 animals are chickens.
Then, there would be 36×2=72 legs in total.
Step 2 (S): Subtract) Clearly, 72 legs is too few.
In reality, there are 124-72=52 legs more.
Step 3 (S): Subtract) 4-2=2
Each rabbit has 2 more legs than a chicken.
Step 4 (D): Divide)
The extra 52 legs must be due to the rabbits, and each rabbit contributes 2 more legs.
Hence, there are 52/2=26 rabbits!
There must be 36-26=10 chickens then.
During the GEP Exam Paper, checking is essential to avoid careless mistakes. 26×4+10×2=124, which tallies! Hence, we are right!

Lastly, do check out our GEP Recommended Books which may be the most useful books on the market (not found in Singapore since most major bookstores like Borders have closed down).
Scientists have proven that IQ can be increased, and hence reading a book like Match Wits With Mensa: The Complete Quiz Book would increase your score in the GEP Exam Paper (Logic) section during the GEP Screening / Selection Test.
