This time around, the puzzle is a maths question taken from a Grade two exam.

“There were some people a train. 19 people get off the train at the first stop. 17 people get on the train. Now there are 63 people on the train. How many people were on the train to begin with?” reads the question shared on Twitter by Louise Bloxham, a mom who couldn't believe the question directed at her six year old.

Twitter user Robyn Duckworth even came up with a theory to solve the puzzle: if you deduct 19 from the 65 passengers adding 17 to get a total of 63 passengers.

Though the answer seemed convincing, Neil Hughes and Lewis Haddow maintained that the answer was 65 passengers; using this algebra equation: X – 19 + 17 = 63.X = 65.

Even more confusing, the mother insisted that the answer was definitely 46 saying the answer was posted on a teenage forum page on Facebook.

Simply put, one user suggested ignoring the 19 passengers. Coming up with this solution; 63 – 17 = 46.

But according to MailOnline, the solution to the problem is in fact 65.

“You arrive at by subtracting the 17 people who just boarded from the current number of passengers, 63, to get 46. Then you add the 19 passengers who got off to arrive at 65."

While the maths test proved to be rather difficult, it’s not the first time the internet have been left puzzled over a brainteaser.
