This percentages maths hack is blowing 100% of people’s minds everywhere

Here’s a maths hack that we reckon you’ll wish you’d have learned back in the day. And when we say ‘back in the day’ we mean when you were at school.

It went viral after it was shared by the good people of @todayyearsoldig on Twitter for reasons which will become apparent.

100% mind blown (and we didn’t need a calculator to work that out).

Just in case you wondered how this works …

But we’re with this person.

This person thought they spotted a flaw.

Except …

Some people still weren’t impressed.

Tough crowd.
