How the riddle truly works—breaking it down simply
Let’s number the siblings to clarify: let Y be the youngest’s age. Then the middle child is Y + 3, and the eldest is 2Y (twice the youngest). Together:
Y + (Y + 3) + 2Y = 42
Combining terms:
4Y + 3 = 42
4Y = 39
Y = 9.75? Wait—no. That math is off. Let’s recheck.
Understanding the Context
Wait—4Y + 3 = 42 → 4Y = 39 → Y = 9.75? That contradicts the headline’s implied integer ages.
Actually, reading carefully, the puzzle as stated leads to non-integer ages—so likely a slight misstatement. But for accuracy and realism:
Try:
Y + (Y + 3) + 2Y = 42 → 4Y + 3 = 42 → 4Y = 39 → Y = 9.75 → invalid for ages.
But if we assume a nearby real-world version—e.g., sum = 43? Or clarify conditions—real math yields non-integer, so puzzle
