# 5 Most Popular Tricky Questions which is Fun to Solve

Maths is fun! Game which you always enjoy and the challenge which you always want to take. Here you have the best and most popular Maths questions which are super viral on Internet. Try if you can crack it.

## 2. Known as “Cheryl’s Birthday,” this is one of the most famous homework questions in the world.

Reached to 10s of million of people, they engaged for hours to solve but most of them failed. Most of them means more than 99%, try and get the answer.

## 3. This problem caused controversy.

After this tweet unexpectedly went viral, people were quick to assume that there had been some sort of mistake. If it takes 120 people to play a 40-minute song, how long would it take 60 people to play the same song?

## 4. Apparently, 80% of kids were able to answer this brainteaser, which has a geographical element.

National Geographic used this puzzle in their show “Brain Games.” They also stated that 80% of kids were able to answer which way the bus was driving immediately.

## 5. Grammar can be tricky for everyone, not just kids.

If you think that the right answer to all of these questions is option three, you’re not alone. However, it’s actually option one for all of them.

Try the question, people have tried and left the question by saying it’s wrong. Do you also think the same?

This is way too vague to be an acceptable question. All the problem states is that Janell lost “some” of her marbles. There is literally no way to know how many she has now.

When the problem hit Reddit, a wealth of answers came flooding in, including “some,” “15 – n {n ∈ ℤ | 1<n<15}.

The simplest answer is < 15, but even that is a little abstract for a third grader.

Kenneth Kong, a television host in Singapore, shared a photo of this 9th grade-level math question in a since-deleted Facebook post, which was shared nearly 6,000 times.

In the logic puzzle, Cheryl gives her friends Albert and Bernard different clues as to when her birthday is out of a selection of dates. She tells Albert only the day and Bernard only the month of her birthday.

By making a table of the dates and using the process of elimination, one can determine that Cheryl’s birthday is July 16.

It was later revealed that this problem wasn’t a regular test question used in Singapore classrooms. It was actually used in a contest as part of the Singapore and Asian Schools Math Olympiad (SASMO).

The New York Times published a detailed explanation of the solution, which you can read here.

After this tweet unexpectedly went viral, people were quick to assume that there had been some sort of mistake. If it takes 120 people to play a 40-minute song, how long would it take 60 people to play the same song?

If you said 80 minutes, you’re among the majority, but still wrong. A song is 40 minutes no matter how many people are playing it.

The original author of the question explained that it was just a trick question to keep her students on their toes.

National Geographic used this puzzle in their show “Brain Games.” They also statedthat 80% of kids were able to answer which way the bus was driving immediately.

Still stumped? It depends on where in the world you are — in the UK, you drive on the left side of the road, so the bus must be traveling towards the right (a bus’ door always points to the curb). On the other hand, if you live almost anywhere else, the bus is heading to the left.

If you think that the right answer to all of these questions is option three, you’re not alone. However, it’s actually option one for all of them.

This is because of the subject-verb agreement rule— a singular noun (Mark, Jacob, the trial) should be followed by a singular verb.
