In a certain country ½ of 5 = 3. If the same proportion holds, what is the value of 1/3 of 10 ?

Why this works

This riddle plays with unconventional mathematical logic. In the phrase "½ of 5 = 3," the riddle suggests that instead of using standard arithmetic, we should look for a pattern or a rule specific to this "certain country." Here, if we interpret "½" as a way of rounding up, then half of 5 (which is 2.5) rounded up gives us 3. Following this same logic for 1/3 of 10, we first calculate 1/3 of 10, which is approximately 3.33. If we round this up, we again arrive at 3. Hence, in this riddle, the answer is derived from the idea of rounding rather than precise division, making it a playful twist on mathematical expectations!
