There is one more solution, I can think of.

May be both of them borned on 1st March and they were living in different timezone when they celebrated their birthday, which made terry celebrated birthday after 2 days of Kerry.

I think this could be a second answer because it doesnt say they celebrated it at the same place.

Thanks.

that isn't quite possible. assuming you live on earth and assuming you were both born on the same day. then it must follow that your birthday must be celebrated within 23 hours. There cannot be a 48 hours timezone difference. Even if you were continuously moving to different timezones to change the time of reference, it doesn't eliminate the fact that the birthday started at what time in what zone.

Clearly, the brother, a fraternal twin, was simply born later.

This is not true because the puzzle states that the brother is older. So, he had to be born earlier. This is why the crossing of the dateline is required. Of course, it does not really have to be the dateline

I agree with rayne1984 and puzzlewuzzle's solution as well. The ambiguity af the language does not clearly specify that the brother and sister are twins, just that the brother is a twin.

The leap year answer is agreeable, also the one above this posting could be true.

There is also an American solution:
The mother could be in an ambulance traveling on her way to a hospital that is in a different time zone (such as in the border town, Gary, Indiana). She could deliver the older son at 12:05am on March 1, in the ambulance, on the way to the hospital. Then, she could cross the time zone so as to arrive at the hospital at 11:30pm on February 28 and deliver the younger son.

Actually there is another solution. There was a rare case in America where a mother became pregnant some 6 months after she had already concieved. Since both children were in the womb together they are classed as twins though there birthdays were months apart. As far as I know both children were completely healthy


This is not humanly possible. As anyone who has ever given birth can attest, once a woman goes into labor WHATEVER is in her womb will be expelled - regardless of time of conception.

There is another solution to the puzzle, though. Let's take a look at how it's worded:

One day Kerry celebrated her birthday. Two days later her older twin brother, Terry, celebrated his birthday. How come?


Terry (and his twin) could very well be older siblings to Kerry. There is nothing in the puzzle that states Kerry and Terry must be twins of each other.
