Here is an interesting problem to keep your brain cells fight boredom on this Friday & weekend.
Let’s say you have some data like above.
And you want to know, for a given customer name (in cell G4),
- What is the most frequent quantity?
- What is the most often purchased item?
How would you write formulas to get these answers?Continue »
Time for some logic check.
Suppose, you have three logic values in A1:C1 (TRUE or FALSE values in each cell)
You need to find out if ONLY two of these values are TRUE.
How would you write the formula?
Got an answer? Awesome. Just post your formula in the comments. Let’s see how much variety we can get from all of our readers.Continue »
Let’s say you have some employee data in employee name, manager name format. But the data is all in one column, with odd rows containing employee names & even rows containing manager names. Something like above.
And you want to find out who is the boss for a given employee. Say, “Andrea Nichols”.
Your regular MATCH() formula for Andrea over the data range returns wrong answer as it will find first occurrence of Andrea (which in this case happens to be on even row, hence a manager record).
So how would you write the lookup formula?Continue »
Finally, spring weather showed up in Wellington this week. We cashed it as much as possible by going on treks, cycling trips, more treks and of course doing laundry.
Anyways, I don’t have time to blog. I must go out and help kids with some cycling. But I want to keep you busy this weekend. So here is a fun homework problem.
Does my range have all numbers from 1 to n?
Let’s say you have a range called range (duh!). And you want to check if range has all the numbers 1 to n (say n=5) in it, each number appearing only once (no more, no less). You can assume the named ranges range and n in your formulas.
See above examples to understand the problem.
So go ahead and post your formulas in the comments section. I will sneak in whenever I can to look at all your creative answers.Continue »
First a little back story:
Last Friday (on 29th of July), we (Jo, kids & I) went on a day walk to Red Rocks. It is a rugged coastal walk near Owhiro bay in Wellington. It was a windy & cold day. So why did we brave the elements of nature on this 10km walk? To see seals of course. And we did find a few of them. We also caught glimpses of snowy peaks in Southern Island of New Zealand.
3 Seals Excel Puzzle
Now I can’t take you on the same walk thru internet. There is no Excel function that can teleport you from your office (or home) to Owhiro bay. So I made the next best thing.
