Only a few months back, some colours on a dress created havoc on the internet. A new math problem has surfaced which is now creating the headlines on the world wide web. The math problem first showed up on Facebook when a Singaporean television host ‘Kenneth Kong’ shared it. People have been attempting to sort Cheryl’s birthday ever since.

When is Cheryl's birthday

The words used in the script are the real problem here. Here is a look at the logic of the math problem:

Albert and Bernard just met Cheryl. “When’s your birthday?” Albert asked Cheryl.

Cheryl thought a second and said, “I’m not going to tell you, but I’ll give you some clues.” She wrote down a list of 10 dates:

May 15, May 16, May 19

June 17, June 18

July 14, July 16

August 14, August 15, August 17

“My birthday is one of these,” she said.

Then Cheryl whispered in Albert’s ear the month — and only the month — of her birthday. To Bernard, she whispered the day, and only the day.

“Can you figure it out now?” she asked Albert.

Albert: I don’t know when your birthday is, but I know Bernard doesn’t know, either.

Bernard: I didn’t know originally, but now I do.

Albert: Well, now I know, too!

When is Cheryl’s birthday?

It was later discovered that the math problem was meant for high school students for an upcoming math olympiad. Once can only imagine what a tough nut to crack such a problem would be for fifth graders. No fifth grader deserves to be mentally abused with such a thing at such a tender age, right?
