Can You Solve This Viral Brain Teaser? How Much Do a Horse, Sheep, and Frog Weigh Together?

If you’re someone who loves a good puzzle, then there’s a brain teaser making waves online that might just be your next challenge. Shared by Instagram’s Threads user @katherine_kat131, this puzzle is simple in its setup but tricky enough to get people talking.

The riddle is straightforward: A frog and a sheep together weigh 10 kilograms. A frog and a horse weigh 20 kilograms, and a sheep and a horse tip the scales at 24 kilograms. The question is, how much do all three—frog, sheep, and horse—weigh when combined?

It’s the kind of problem that makes you pause and think, and that’s exactly what happened when it hit the internet. The post, titled “Can you solve this?”, quickly went viral, drawing puzzle lovers into a friendly debate.

One of the most popular answers came from a user who broke down the math: “It’s 27. Add up the three pairs—10, 20, and 24—and you get 54. Since each animal is counted twice, you divide by 2, and that gives you 27.”

Others chimed in with their methods, and while most agreed on 27 kilograms, a few couldn’t resist adding some humor. One commenter joked, “I’ll go with 0 and infinity since we don’t know how much a letter weighs!”

But not everyone saw it the same way. A different take suggested, “I got 27. There’s a 4kg difference between the frog and sheep, so if the frog weighs 3kg and the sheep 7kg, then the horse must weigh 17kg. Adding those together gives 27.”

Despite the variations, the community seems to have settled on the answer being 27 kilograms. However, a small group still thinks the total could be 29 kilograms, adding to the puzzle’s mystique.

Whether you’re a math whiz or just someone who enjoys a good mental workout, this brain teaser has certainly sparked some fun discussions. So, can you solve it?
