Hello, jak!

What a silly problem!

Where did it come from?

Quote:

Mandy is 25 years older than Sandy.

Sandy is 25 yrs younger than Mandy. . . . . well, duh!

Mandy's age is even. . . . . Not relevant

Sandy's age is odd. . . . . . Who cares?

Together the sum of their ages is 63. . . . . Finally, something useful!

How old is each sister?

They're sisters? .Boy, that's really important!

(That's quite an age spread for siblings, isn't it?)

Then = Mandy's age.

"The sum of their ages is 63": .
