This riddle has been around for some time on internet platforms such as Instagram, Facebook, and WhatsApp, and many people still argue over what the answer might be, as there are many possibilities. The correct answer is 72 buses. Let’s say before expansion, the garage can handle X number of buses. By increasing the garage space to 40%, they will have room for the 12 buses after expansion plus another 12 in the future. So, we can come with the equation: 1.4X = X + 12 + 12 Solving for X will give 60. By adding the 12 buses that were stored outside, we can get a total of 72 buses. The garage will have room for another 12 buses.
