OLIVER WYMAN NUMERICAL REASONING TEST EXPLAINED - Videos

[LINKS TO MATERIALS BELOW]
In this video I solve an Oliver Wyman-style numerical reasoning test. I cover equations, probability, geometry, compounding, and some other question types. The video is long, so feel free to save the link for future reference and watch in several sittings.

The test is a challenge since you have only 30 mins to deal with all the questions I cover in this long video. So practice. Pause the video on each question, try to solve it on your own, and only then watch the solution.

If you have any comments, please share. And please like it if you find my video useful!

[ERRATA CORRIGE] – Known mistakes fixed:
00:02:43 My interpretation of Insta’s growth is wrong (thanks to Elchin Karimov for pointing out). Insta’s downloads increase is not 10k but rather [prev. month increase] + 10k. That means the following dynamics: J 300, F 310, M 330, A 360, M 400, J 450, J 510 and so on.
00:04:08 Given previous comment, my calculation of Clapchat’s downloads in April need to be more precise: not ~330+/-10, but ~345. Then it becomes obvious that Clapchat’s May value overtakes Insta (345*1.2 is greater than 400). Hence the answer is (B) May
( Please report other dubious points )

  1. Привет, Виктор. В 1 задаче разве не прирост на 10к увеличивается каждый месяц? Т.е. первый месяц +10к, потом +20к, +30к и т.д. Таким образом будет 300 310 330 360 400 для insta.
