Here’s a classic riddle involving a family with five daughters. Mary’s dad has five daughters, and their names are Cha, Che, Chi, and Cho. The riddle plays with the pattern of the names to trick you into thinking of a fifth name that fits the sequence.
But if you pay close attention to the phrasing, you’ll see that the answer is hidden in plain sight. Since the riddle begins with “Mary’s dad,” it indicates that Mary is the fifth daughter.
Answer: The fifth daughter is Mary.
