Oh, I missed that one. Will take a look at it right away.

Thank you sir. 🙂

1) “80 x 1.2 = 96”

When you take 120% (or 1.2), it includes the original amount plus the “increase” or change. 100% is for the original amount and 20% above it is the “increase”.
The answer to the calculation will include initial/original amount as well as the “increase” and you will not have to add 80 separately.

2) “80 + (80×0.2) = 80 + 16 = 96”

On the other hand, when you take only 20% (or 0.2), it is just the “increase” or change.
That is why you have to add the original amount (the first 80 in “80 + (80×0.2)”) to the calculation separately.

I am not an expert at explaining things, but hope that helped.

Oh, and your calculation is not correct, “120/100” is the same as “1.2” or “120%”
You can not take 120% and add 80 as well.
Either
1) multiply by 120% and don’t add 80; or
2) multiply by 20% and add 80.

I’m going to take F4 for the third time this December while I passed all the other fundamentals upto F7 on the first go. And I’ve realised you can not get away without reading and reading and reading, as Mike said, the torturing text, until you can’t find anything you haven’t already learned in the past exam questions.
I’m wondering if I’ll follow this advice myself this time, have a really bad memory with words, but goodluck to you. 🙂
