Easy high quality question. Just remember to use the calculator to speed up the percent change question.

I did not have the benefit of a calculator on my GMAT so that was not an option but I have trained myself to be faster than a calculator (even the physical one rather than a dinky on-screen one) so I would say you should usually be able to beat the calculation by doing it in your head (unless your mind is stuck for some reason due to time panic/etc - it happens and in that case, a calculator is very handy to break through that)

that’s a good question. I’m not sure I can easily explain because it was subconscious calculation 😬

But I saw that the difference was 4000 with some dollars. 4063 to be exact.

I knew right away that 4000 out of 50,000 would be 8% it would actually be slightly greater if you take 50,000 as the base and each additional percent would be 500. But I didn’t have to do those calculations or think about it, it just all happened automatically in my mind from years of calculating things in my head.

However, there is no difference however you arrive to a correct answer as long as it’s efficient and consistent. I think it’s totally fine to go out and get a solid answer. Once and move on if that works for you. The most important part is probably not how you do it but how you do it consistently and ensure that you stick with your patterns so you don’t Flip things around. Make it robotic and muscle memory and whether that means using a calculator or running through it in your mind, I can both ways work.

no idea if I explained anything 😂

I agree with your point, I made a mistake exactly because of this, took 7 instead of 8 in this question. I think it's not consistent that GMAT is pushing us to do mental math and approximation in some type of questions, and presice calculation in other types. And not everybody's mind is mathematical, + exam stress, etc. I hate the on screen calculator, and our exam centre would not give us calculator to use for all the time during DI section, I have no idea why! Couldn't find any restriction on that, will report them if they come up with the same thing next time.

You can only use the onscreen calculator for the data insights section, both at the test center and for the tests taken online.

Isn't that inconvenient or is it just me?

Thanks anyway!:)

Yes, I would agree with you. Using on line calculator is time consuming and inconvenient. Only way out is to get used to it in mocks. Also, there are very few questions where you would actually require it. I was forced to take four official mocks in last four days as the expiry was 13 this month, and I didn't use the calculator even once. So majority are doable on scratch pad.

And to add one more thing - the onscreen calculator is very basic. It has only the most basic operators. But there will be very few questions in which having a calculator will be useful. In most cases, observation and estimation are sufficient. So much so that many learners forget that they have access to a calculator! In 1 or 2 questions though, it may be useful so try it out during mocks.
