Logic Puzzle Challenge


"I've always been 45 years older than your Dad", said Grandma to
young Rish. "But now the two digits in my age, both prime, are
the reverse of the two in your Dad's age". How old is Grandma?

  5. The age of the grandma is 72. 7 and 2 are both prime. The fathers age is 27. 72 and 27 are 45 digits away from each other.

    72-27=45

  6. Grandma is 72, (young) Rish's father is 27. It was hard not to see these spoilers, but I did actually work the problem out for awhile, I don't just copy.
