Consider, the items are: 22, 40, 64, 70, 90
I haven't take a look, so chances of mistake would increased.
Actually, in real items were: 20, 40, 65, 70, 90
Financially literate means a lot in daily life, if we are, then it is advantage if not, then we can make mistakes at several instances.
My habit is to in hurry, which can create a mess in certain situation and can lead to wrong values/answers, so it is bad.
Hope this helps!
