A: "You've got two boys and two girls. How old are they?" asked Steve.

"It's odd you asking, because my older son Pete noticed a coincidence about their ages last night," Clem replied. "The square of his age, added to my age, makes the square of Susan's age added to Betty's age. And the square of Paul's age, added to my age, gives Susan's age added to the square of Betty's age."

"Okay, that's all I need," Steve chuckled. "I know you're thirty-five yourself."

He was right, so what were the four ages?

B: "You've got just the three kids, eh?" John commented. "I met two of them at your party."

"That's right, Sam and Betty," Ken replied. "You can figure out their ages. The sum of the squares of the boys ages is what you get if you subtract the product of their ages from the square of their sister's age. And she's two years younger than the sum of the boys' ages."

You try!
