I came across a case where I had to do the following calculations:
- 6090 / 12
- 29600 / 12
- 20181 / 12
I know I can do this with long division but I feel it takes too long. Is there a more efficient maths formula/technique to solve these?

Hi there,
What you can always do is to divide the denominator further.
Basically:
6090 / 12 = 6090 / 4 * 3 = 6090 / 2 * 2 * 3 = 3045 / 2 * 3 = 1015 / 2 = 507.5.
Happy to share a few additional resources on improving maths speed - reach out.

Hi there,
If this pops up in a case question, my first question would instantly be if the interviewer expects an exact answer or if you can round the numbers (which 99% of interviewers will agree too).
Then change it to 6000 / 12, which is 500. Fairly simple and takes less than 10 seconds.
Cheers,
Florian
You should round here.
6090 / 12 is essentially 6000 / 12.
Which is 3000 / 6
Which 1500 / 3
Which is 500
Yes, just round the numbers. No one will ask you to calculate the exact number. We're looking for analysts who can use calculation tools, not human calculators.
