WATCH: Group of young boys get hilariously fooled by simple math riddle

Headlines 10/06/2019

Some days it's just not your day.

That's what a group of young boys have learned after finding themselves completely fooled by a simple riddle in a video posted to social media over the weekend.

The riddle goes as follows:

If I was 6-years-old, and my sister was half my age, when I am 70, how old would my sister be?

The first answer your brains goes to is probably 35, which is incorrect, but understandable if that's your FIRST answer.

But unfortunately for the boys in the video, that's the only answer they could think of. The group then hilariously argue amongst each other, getting the answer wrong every time.

The answer, for those of you who are still struggling, is 67. Because when you are 6 and your sister is half your age, she is 3, meaning she is 3 years younger than you. She is only half your age at that exact point in your life, not for the rest of your life. So when you are 70, she is still just 3 years younger than you, making her 67.

See? Easy.
