Korn Ferry numerical test: choose the right practice
Korn Ferry's candidate guide covers four abilities, so your invitation matters more than the publisher's name. Korn Ferry describes the numerical one as analysing statistical data and making decisions from sets of figures. Below is one question of that kind, with the working after it.

You have an invitation with Korn Ferry’s name on it, and maybe not much time. There are two things to be ready for: what the test looks like, and whether your maths is quick enough. They need different preparation, and this page helps you tell which one to work on.
If your invitation already names a numerical assessment and you only want untimed drills, they are in our numerical section.
Work out which assessment you were given
Korn Ferry’s candidate guide covers four abilities: verbal, numerical, logical and checking. The publisher’s name on its own does not tell you which one you were given, and they are not interchangeable. Time spent on numerical questions does nothing for the verbal test.
If your invitation does name numerical work, you know what you are preparing for. Korn Ferry describes that one as analysing statistical data and making decisions from sets of figures.
If it only says Korn Ferry, or mentions Talent Q without naming the assessment, you still do not know which of the four you will sit, so there is nothing worth practising yet. That is worth five minutes: read the instructions that came with the invitation, or ask the recruiter what the assessment is called. On the day, your invitation and the instructions on screen are what count.
Try this before you read on
Work it out before you open the answer. The three wrong options are not filler: each one is a different calculation route.
Practice question
A supplier recorded 250 orders in March and 320 orders in April. By what percentage did the number of orders change?
Our question, written for Testonome practice. Nothing you decide here is recorded.
Check your answer
B, 28%. Subtract first: 320 − 250 = 70 orders. Then divide by March, the month the change started from: 70 ÷ 250 = 0.28. As a percentage, that is 28 percent, a rise.
Each of the other three comes from one wrong move. 21.9% divides by April instead of March, so you have measured against where the change ended rather than where it started. 70 is the change in orders, so the subtraction is right but the unit is wrong. 128% is April compared with March, which tells you how big April is, not how much it moved.
What to do next
If you picked one of the other three, the explanation above shows the route that leads to each one. Any of them is worth a few more questions on the same skill, and our percentage-change page sets the method out first if you would rather read it before practising.
If you got 28% but guessed, or cannot repeat the three steps now, the same applies. Getting it right once and being able to do it under time pressure are different things.
If you got it and can redo it, a few more questions will tell you more than this one did. One question settles nothing either way.
Closer to the day, there is one more thing worth doing. Korn Ferry’s candidate guide has a practice assessment of its own, and that is where you see the publisher’s screen and controls.
The button below opens the percentage-change drill: five original questions, untimed and free to use, each one worked through after you answer, with no account and no payment. It also suggests a target time for the calculation, which is our own pacing for this skill.
