International Numerical Reasoning Contest 2018

!- BEFORE PROCEEDING WITH THE TEST, READ PROVIDED DESCRIPTION AND INSTRUCTIONS. -!

Description : INRC 2018 consists of 30 numerical sequences, that have to be answered under no time limit. Test requires numerical pattern recognition ability; advanced knowledge is not required (only that of elementary procedures).
Instructions : Please do read carefully the following:

  • Sending answers : Answers can be sent through email (to ngtfinal@yahoo.gr), using this answersheet, until November 30th, 2018. One submission is allowed.
  • Use of references is allowed but most likely won’t be of any use. Do not, however, discuss items or your answers with anyone. Publication of answers is strictly prohibited.
  • Identity verification : One must prove their identity by sending a scanned copy of their ID or passport or driving license or any other relevant documentation. Name, surname, age and nationality must be visible and written in latin characters. Other details can be covered/distorted. If someone does not wish or cannot send the aforementioned documentation, another way of proving one’s identity, is by sending some symbolic fee through paypal (eg. 2-3 Euro), to ngtfinal@yahoo.gr.
  • Fee : No fee required for this Contest, except if one wishes to donate or verifies their identity through paypal.
  • Top 50 scorers will be listed in the relevant list.
  • If anyone wishes to try this test without taking part in the Contest (without being listed), it is possible by sending a fee of 5 Euro to ngtfinal@yahoo.gr
  • All contestants are entitled to a free submission on NPRA36, as a symbolic prize for their participation. More prizes, like monetary ones, will be announced in the future.

-! There has been a misconception in item 24, which is now corrected. Thanks to Alfredo Leggieri for noticing it.
