A is three times as old as B. C was twice-as old as A four years ago. ...

We have : A = 3B ...(i) and
C – 4 = 2 (A - 4) ...(ii)
Also, A + 4 = 31 or A= 31 – 4 = 27.
Putting A = 27 in (i), we get: B = 9.
Putting A = 27 in (ii), we get C = 50.

Fishing With Granpa LeonRonan was beside himself with excitement. He was ten years old and his Grandpa Leon was finally going to take him fishing. Grandpa Leon claimed to be “a fishing expert, practically a professional angler.” He told Ronan that he’d caught giant marlin and huge tuna and that he had many adventurous stories to tell. He promised he’d supply all the fishing gear: rods, reels, hooks, bait, buckets, and plenty of food, too. All Ronan had to do was to be ready promptly at 6 am.As it happened, it was good Grandpa Leon brought plenty of food because grandfather and grandson had plenty of time to eat it. The fish simply weren’t biting. “They’re napping,” he informed Ronan, knowingly.No nibbles left plenty of time for Grandpa Leon’s elaborate fish stories. In fact, it was during one of those tall tales that Ronan suddenly felt a sharp tug on his line. “I’ve got something really huge!” he shouted.“Hold tight, I’ll help,” Grandpa Leon replied, reaching over and grabbing the rod. Together, they tugged on the line that held what promised to be a colossal, prize-winning fish. Finally, they reeled in their catch—a tattered leather suitcase, heavy with sand.“How about that, Ronan—the first suitcase of the day!” GrandpaLeon exclaimed, adding, “You can’t say it wasn’t a big catch!”Q. Which best describes what anglers do?

The Record SetterMy brother, Alex, is generally considered to be a reliable, clever, thoughtful fellow. I say “generally” because of things like what he’s doing right now.Picture this and you’ll understand. While I, Nate, sit here playing a video game and texting with half my friends—two perfectly normal things to be doing for amusement—what is he occupied with? Alex is standing over there, counting softly to himself 79, 80, 81, 82… while he repeatedly bats a rubber ball attached by an elastic string to a wooden paddle. This is nonsensicalbehaviour, is it not?You might think I’m being too hard on Alex, asbrothers sometimes can be to one another. On the contrary, I’m being lenient. You see, this time it’s paddleball batting, but the last time—and I refer to just a few weeks ago—the challenge was standing on his head foras long as he could, with a timer set up on the rug. Of course, he had to read it upside down, but I suppose he got better at it day by day. Maybe he should’ve put the timer upside down, too.Frankly, I’m getting a bit concerned. What if one of his goofy pals introduces him to alligator wrestling? Or what if he gets enticed to take up tightrope walking from skyscraper to skyscraper? I tell you, for Alex, these ideas are not too far-fetched!Q. To amuse himself, Nate likes to…
