## How many employees are on leave during Easter holidays [Homework]

Published on Apr 7, 2017 in Excel Challenges

Easter is around the corner. After what seemed like weeks of lousy weather, finally the sun shone today. I capitalized on the day by skipping work, walking kids to school, taking Jo out for some shopping, enjoying a leisurely walk / cycling with Nishanth in the park and almost forgetting about the blog. But it is dark now and before tucking the kids in, let me post a short but interesting home work problem.

Let’s say you are HR manager at Egg Co. and you are looking at the vacation plans of your team.

Easter is your busiest time and it would be a bummer if a majority of your staff are on leave during the Easter season (14th of April to 28th of April, 2017). So you want to know how many people are on leave. A snapshot of your data (table name: lvs) is shown above.

You want to answer below three questions:

1. How many employees are on leave during Easter holidays (14th of April to 28th of April)?
2. How many employees are on approved vacation during Easter holidays?
3. How many employees in “Team ninja” are on approved leave during Easter holidays? Assume team employee numbers are in named range ninja

## How fast can you finish this Excel Hurdles Challenge [Spreadsheet Olympics]

Published on Aug 10, 2012 in Excel Challenges, VBA Macros

Watching the Olympic athletes run & jump all I could think of is,

• What should I eat to jump & sprint like that?
• How come I never heard about steeple chase?
• Should we really have 3 bullet points in all lists?

But I digress. Coming back, when watching one of those hurdles events, I got an idea as sharp as Chinese table tennis team.

Why not create a hurdles game in Excel to measure how good you are with keyboard?

So ladies & gentleman, let me present you our very own Olympics hurdle run.

## Get busy this weekend, with OR XOR AND [Excel Homework]

Published on Jul 29, 2011 in Excel Challenges, Excel Howtos

Some of you have heard my neighbor’s dog bark in a video or two that I recorded. While I was busy explaining how to do something awesome in Excel, this dog would decide to bark, adding her own two cents to the lesson. Quite a few of my VBA class students have grown used to it. So much that they complain when a lesson doesn’t have a couple of woofs. But I digress.

So coming back, one of the dogs (probably stray) has decided that she should bring her infant puppies and hide them under our terrace stair case. So, now we have 2 cute little puppies barking day long (and very late in to the night) just outside my office window. We have tried hard to get rid of them, but they somehow sneak back in and start barking or crying. So, I will be busy this weekend trying to move them out.

But that doesn’t mean, you have to live Excel-less for a few days. So I have a homework.

### OR XOR AND, Get busy this weekend!

Don’t worry. I am not speaking elvish or something. OR, XOR & AND stand for bit-wise operations. This week, your task is to write formulas in Excel that would get the bit-wise results for AND, OR & XOR.
