> Problem 92 Dad took our new baby to the clinic to be weighed. But the baby would not stay still and caused the needle on the scales to wobble. So Dad held the baby still and stood on the scales, while nurse read off their combined weight: 78kg. Then nurse held the baby, while Dad read off their combined weight: 69kg. Finally Dad held the nurse, while the baby read off their combined weight: 137kg. How heavy was the baby?

- diplodocusaur 5y agoIf Lana was 31 years younger, she'd be 12 times as old as her baby. Lana is half as young as Robert, who is 44. Find the baby.
- coolgeek 5y agoThere are two Lanas. The first Lana is (probably) 43yo, and her child is 1yo. But they could (in theory) be 55 and 2, 67 and 3, 79 and 4, 91 and 5, 103 and 6 or 115 and 7. The second Lana is 22. Oh, wait... the task was to find the baby. Hey, what's a good regex for matching open tags except XHTML self-contained tags?
